The Hammers manager Bilic said, "I said at the end of last season that we don't need squad players, but we need top players, the players who are going to improve the first eleven". West Ham is a historic club, and very ambitious - this summer you can see with the players signed that they are looking to have a very good season.
And, some West Ham fans posted amusing Tweets in the days leading up to Chicharito signing for West Ham.
Hernandez - who returns to Old Trafford for Sky Sports' first Super Sunday bill of 2017/18 - admits he was "desperate" to return to the Premier League and wants to repay West Ham boss Slaven Bilic for making consistent efforts to sign him.
Hernandez is set to make his Hammers debut against his former side Manchester United on the opening weekend of the Premier League season.
Marko Arnautovic says he joined West Ham because he believes they've shown more ambition than his previous club Stoke. Overall, his time in Germany saw him score 28 goals in 54 league appearances. Despite an 11-match barren spell last season, he still netted 13 times for Bayer Leverkusen in the Bundesliga. "But, no doubt, for West Ham to get a player with his experience and quality is very, very good".
For instance, of Chicharito's 72 goals scored since moving to Europe, 68 have come from inside the penalty area. "West Ham and the national team are the only teams I care about this season".
A Carroll-Hernandez partnership will therefore prove much more effective than a formation including only one striker, with both strikers needing a partner to impress.
Zabaleta, Hart, Arnautovic and now Hernandez.
