West Ham United most expensive signings - How Hammers spent over £950 million on incoming transfers

After a one-season spell at Swansea in which he scored 12 goals in 34 appearances, Ghana international Ayew joined West Ham in the summer of 2016.

The striker arrived for a then club-record fee of £21.69 million on a three-year contract, with an option of extending it for a further two years.

After making 43 appearances and scoring just nine goals, Ayew returned to Swansea in 2018 for a £20.52m fee.

Born in Toulouse in France, Diop went on to feature for his local club at youth level before making his debut in 2015, aged just 18.

The centre-back scored his first goal in just his second game for the senior team and helped Toulouse avoid relegation that campaign.

Towards the end of his spell at the club, Diop was made club captain and helped them reach the quarter-final of the Coupe de France.

The 2017-18 campaign was his last season at the club before West Ham came calling in June 2018, agreeing to pay £22.50 million for his signature.

After four years at the club, Diop moved to Fulham in the summer of 2022 for a £16.02m fee.

Fornals arrived at West Ham on a five-year contract from Villarreal in the summer of 2019 for £25.20 million, making him their second-most expensive transfer at that time.

His debut came in a 5-0 thrashing at the hands of Manchester City, a game in which he came on as a substitute in the second half.

Since 2019, Fornals has made well over a 100 appearances for West Ham.

Croatian attacking-midfielder Vlasic signed for West Ham from CSKA Moscow in the summer of 2021 for £27 million on a five-year contract.

However, he only appeared for 552 minutes over 19 games in his first season at the club.

Due to immense competition in the attacking midfield space at West Ham, the former Everton man moved to Italian club Torino on a one-season loan in the summer transfer window of 2022.

After impressive defensive performances for Ligue 1 side Rennes in his 66 games at the club between 2020 to 2022, West Ham signed Aguerd for £31.50 million in the summer of 2022.

In a pre-season friendly against Rangers in July, Aguerd suffered an ankle injury that required surgery and fans still eagerly await what the the Moroccan international can do.

After never really quite becoming an undisputed starter at Chelsea, Zouma made the move to West Ham in August 2021.

The Hammers paid £31.50 million for the French centre-back, who then made his debut in the Europa League in a 2-0 win over Dinamo Zagreb.

His first Premier League goal for West Ham was a memorable one, as he scored the winning goal in their 3-2 win over Liverpool in November 2021.

After spending his youth career at the academies of Lazio, Roma and PSV, Italian striker Scamacca joined Sassuolo in January 2017 for £3.69 million.

He was then loaned to Cremonese, PEC Zwolle, Ascoli and Genoa in back-to-back seasons until 2021.

In the 2021-22 season, he returned to Sassuolo and netted an impressive 16 goals in 36 appearances for them in Serie A.

His performances also earned him a call-up to the Italian national team.

West Ham then made a move in the summer of 2022, agreeing to make him the fourth-highest transfer in the club's history, paying £32.40m for his signature.

Brazi international Anderson's name was doing the rounds in European football ever since his rise at Santos.

After being linked to some of the biggest clubs in the world, Anderson joined Lazio in 2013 for a £6.75 million fee.

The attacking midfielder made 137 appearances for them between 2013 and 2018 before West Ham came calling, agreeing to pay £34.20m for his signature.

Anderson, however, could not stamp his authority with the Hammers, making just 53 appearances in two seasons before being loaned to Porto in the summer of 2020.

Lazio returned for their former star in the summer of 2021, paying West Ham a poultry £2.7 million fee.

Lucas Paqueta's name had been doing the rounds in some of the top European clubs' boardrooms ever since he rose to prominence at Flamengo between 2016 to 2019.

Milan were the first team to recognise his talent and they brought him to Europe for a hefty £34.56 million fee in 2019.

However, the attacking midfielder only lasted one season at San Siro before moving to Lyon in the summer of 2020 for a cut-price £21.10m.

At Lyon, Paqueta re-found his best form and several Premier League clubs were quickly circling again.

West Ham saw his immense potential and decided to sign him for £38.66m, making him the second-most expensive signing in their history.

In the summer of 2019, West Ham splashed £45 million to sign Haller from Eintracht Frankfurt in a club-record transfer.

The Ivorian made 48 appearances for the Hammers in his two seasons at the club, scoring 10 goals before Ajax came calling, paying a cut-price £20.25m for the striker.

Haller formed an incredible partnership with Antony and Dusan Tadic at Erik ten Hag's Ajax, scoring 32 goals in 50 appearances for them.

He later joined Borussia Dortmund in 2022 for £27.90m, after which he was diagnosed with a tumour in his testicle. Still recovering, Haller is yet to make his debut for Dortmund.
