Fati, Sancho and the teenage stars to watch in this season's Champions League

With Bayern failing to sign any top-class replacements for Arjen Robben and Franck Ribery over the summer, the weight of responsibility has grown substantially on Canadian international Davies.

While Kingsley Coman and Serge Gnabry remain Niko Kovac's first choice wide pair at the Allianz Arena, Davies is seen as the first reserve – along with Ivan Perisic - and has all the tools to make it at the very highest level.

Ajax may have sold a number of their young stars following last season's run to the Champions League semi-finals, but that has allowed a new batch of teenage stars to break through in Amsterdam.

The most impressive of them so far this season has been right-back Dest, whose performances have been rewarded with a first cap for the senior United States side as well as a fresh contract with the Eredivisie champions.

Few 16-year-olds get the chance to play for Barcelona's first team, and even fewer make the impact that Fati has during the opening week of the season.

In just his second appearance for the Blaugrana he found the net against Osasuna before marking his first start against Valencia with a goal and an assist inside seven minutes at Camp Nou.

It remains to be seen how many chances he gets once the likes of Lionel Messi, Luis Suarez and Ousmane Dembele return to full fitness, but he has certainly made his mark on Ernesto Valverde.

The son of former Leeds United defender Alf-Inge Haaland, the teenage striker has been in superb form for Salzburg in his first full season with the Austrian champions.

Having scored nine times in a game for Norway during the Under-20 World Cup over the summer, he has backed that up with 14 goals in eight games to kick-off the new campaign. He has now earned a first full international cap, and is already being linked to a host of top European clubs.

With talk over his future set to come to an end as he closes in on signing a new bumper contract at Stamford Bridge, Hudson-Odoi's concentration can now switch to further enhancing his growing reputation as one of England's most exciting youngsters.

Already a full international, the wide forward will get his first taste of Champions League football under Frank Lampard once he is fully recovered from the ruptured Achilles tendon he suffered towards the end of last season.

Winner of the Golden Ball at this summer's Under-20 World Cup, Lee is already being dubbed as the natural heir to Son Heung-min for the South Korea national team.

A creative midfielder, it remains to be seen quite how much game time he will be given under new coach Albert Celades following the controversial sacking of Marcelino last week.

Benfica's conveyor belt of talent is almost endless, and right-back Tavares is the latest to make his mark on the first team in Lisbon this season.

Having made his first-team debut in the Portuguese Super Cup, he marked his first league start against Pacos Ferreira with a superb long-range goal as well as two assists.

Already a household name across Europe, Sancho's decision to leave Manchester City for Dortmund has already been more than vindicated with a series of electric performances in the Bundesliga.

This season he has kicked on again, contributing two goals and five assists in Dortmund's first four league matches of the campaign, as well as scoring his first two international goals for England against Kosovo.

Having been signed from Gremio last season, the Brazil Under-20 international has already been likened to Willian as Shakhtar again look to bring through the best youngsters Brazil have to offer.

Naturally left-footed, he predominantly cuts in from the right-hand side and scored twice in the Ukrainian Cup final as Shakhtar secured a domestic double in 2018-19.

One of the very few bright spots to come out of Real Madrid's disastrous season last time around, the signs are that the young Brazilian is set to make further progress under the guidance of Zinedine Zidane.

An electric showing against Levante on Saturday suggested he is about to rediscover his best form despite the arrival of Eden Hazard and rebirth of Gareth Bale at Santiago Bernabeu.
