Best debut seasons at Premier League clubs: Where does Erling Haaland rank after record-breaking 35th goal for Man City?

Michu came to the Premier League as a relative unknown, enjoyed an unbelievable debut season for Swansea and then faded back into obscurity.

Having signed from La Liga strugglers Rayo Vallecano for only £2 million in 2012, the Spanish forward had a dream debut, scoring twice in a thumping 5-0 win at Queens Park Rangers, celebrating by cupping his ear.

By Christmas, he had posted a remarkable 13 goals, including a brace in a shock win at Arsenal, and in February he helped Swansea win the League Cup, netting in the 5-0 rout of Bradford City in the final at Wembley.

He ended the campaign with 18 goals, putting him in the top five Premier League scorers that season. But that was as good as got for him, with ankle injuries disrupting his career and leading him to eventually retire from football in 2017, aged only 31.

Not many players swap Bayern Munich for Blackburn, and Rovers quickly realised they had landed someone special when Paraguay striker Santa Cruz scored within minutes of coming off the bench on his debut at Middlesbrough.

Working under one of the deadliest finishers of his day in manager Mark Hughes, Santa Cruz relished his role as a poacher and became a specialist in arriving around the six-yard box and scoring with one touch.

He netted 19 goals in his first season, making him the fourth-highest scorer in the league and helping Blackburn finish seventh, narrowly missing out on European football.

But he could not keep it up the next campaign, getting only five goals. Indeed, his debut season with Blackburn is an anomaly and the only time he scored more than 10 times in a league campaign in Europe, despite playing for Bayern, Manchester City, Real Betis and Malaga. Santa Cruz is still playing in the Paraguayan top-flight today, aged 41.

Klinsmann was the first genuine foreign star to join the Premier League, and Spurs could hardly believe their luck at landing one of the icons of the 1994 World Cup. The striker instantly endeared himself to the press by asking at his presentation if anyone knew of any nearby diving schools, making light of his reputation for play-acting.

He celebrated his first goal on his debut against Sheffield Wednesday by diving across the pitch and scored an acrobatic volley on his home debut against Everton. Fans were enraptured by 'Jurgen the German', who struck 21 goals over the season.

He was ultimately too good for Tottenham and left for Bayern Munich after just one year. But he had formed a strong bond with Spurs and returned to the club midway through the 1997-98 season, helping them avoid relegation.

Torres was destined to play for Liverpool after wearing an armband bearing the words 'You'll Never Walk Alone' while he was representing boyhood club Atletico Madrid. Liverpool had long been searching for a proper striker since the days of Michael Owen, and Torres was everything they dreamed he would be.

In his first season, 'El Nino' became the first Liverpool player since Robbie Fowler to score 20 times in the league, the first Red to score consecutive hat-tricks since 1946, and the first player to score in eight consecutive games at Anfield since Roger Hunt in 1962.

Only Cristiano Ronaldo beat his total of 24 league goals that season, which was the best goal tally of his career.

After firing Atletico Madrid to their first La Liga title in 18 years, Diego Costa was Jose Mourinho's top choice to lead his second coming at Chelsea. Costa was an enigmatic figure, a player who feasted on goals and was idolised by the Stamford Bridge faithful for his win-at-all-costs mentality, which perfectly chimed with Mourinho.

He scored seven times in his opening four matches, feeding on passes from another new arrival from Spain in Cesc Fabregas. Things turned a little sour when he was charged with violent conduct by the FA for a stamp on Liverpool's Emre Can and a two-month goal drought followed.

He still managed to end the season on 20 goals, and added a Premier League crown to the Spanish title he had won the year before.

Van Nistelrooy was all set to join United the previous year, only to suffer a cruciate ligament knee injury in training for PSV Eindhoven. A year in the treatment room did nothing to drain his power or hunger, though, and he scored twice on his debut against Fulham.

Later in the season, he made Premier League history by becoming the first player to score in 10 consecutive matches, a record which stood for 13 years until Jamie Vardy broke it.

He struck 23 times in his first campaign, just trailing top scorer Thierry Henry by a goal. The Dutchman was an utterly ruthless finisher, scoring 20 league goals or more in four of his five seasons with United.

He only scored once from outside the area, but no one at United seemed to care. And when he was this prolific, why would they?

Cole was just 21 when he made his Premier League debut in August 1993, having helped Newcastle win promotion to the newly-created top flight after joining late in the previous season.

The youngster took the division by storm, firing Newcastle to a third-place finish and topping the scoring charts with 34 goals. Nicknamed 'Cole the goal', the striker was a symbol of Kevin Keegan's highly entertaining side.

But his spell on Tyneside could only last so long, and less than a year later he signed for then champions Manchester United for an English record of £7 million. His 34 goals was matched by Alan Shearer the following season, but their record stood for another 28 years until Haaland came along.

Manchester City were on the rise in their fourth season under their Abu Dhabi ownership and had won their first trophy in 35 years in the form of the FA Cup, but a proven goalscorer was the one piece of the jigsaw they were missing.

Aguero, who signed from Atletico Madrid in 2011 for a then club-record fee of £35 million, was the perfect fit, a classy yet ruthless finisher who could score all manner of goals and create them too. He proved that on his debut against Swansea by netting a tap-in, serving up a goal for David Silva and then smashing one in from 30 yards.

After a stunning start to the campaign tailed off a bit, he came back to life at the most important moment of the season, scoring six goals in the final six games as City chased down Manchester United.

And of course, he capped a stunning first season in the best way possible, lashing the ball home in the 93rd minute against QPR to steal the title off United and give City their first ever Premier League crown. It would not be their last.

After a disappointing spell at Chelsea, Salah revitalised his career in Italy, first with Fiorentina and then Roma. With the help of a private striking coach, he became a prolific scorer in the Italian capital, and Liverpool splashed out a club-record £37 million to bring him back to England.

It soon became apparent it was money well spent. Salah scored on his debut against Watford and in November alone struck seven times. Later in the campaign, he scored four goals in one game, with Watford again the hapless victims.

The Egyptian fired Liverpool to the Champions League final with a goal blitz against Roma and ended the domestic season on a high, netting in the final game against Brighton to secure the Golden Boot and become the first player to score 32 goals in a 38-game Premier League season.

Haaland had put up eyewatering goal numbers at each of his previous clubs, yet there were still some reservations about his ability to maintain his scoring figures in the greatest league in the world, especially after a rusty debut against Liverpool in the Community Shield. He silenced those critics by scoring twice on his league debut against West Ham, though.

He grew hungrier with each game, netting consecutive hat-tricks against Crystal Palace and Nottingham Forest, while more trebles followed against Manchester United and Wolves.

He has scored eight goals in his last six games, shattering Salah's record of 32 goals in a 38-game season and then coming for Shearer and Cole's record of 34 goals in any campaign, breaking it against West Ham.

With five matches left, he should comfortably break the 40-goal barrier, and the only person who looks capable of one day toppling this astonishing campaign is the man himself.
