Manager Slaven Bilic is in the market for a new striker this summer, as Andy Carroll continues to suffer regular injury problems, whilst Enner Valencia and Diafra Sakho both struggled this season.
A consistent goalscorer is needed, and with the new Premier League TV deal coupled with the move to the Olympic Stadium, Bilic should have big money to spend.
A number of strikers have already been linked with moves to West Ham, and now Sky Sports report that West Ham have failed in a move for a top striker.
It's reported that West Ham offered £31m to sign Lyon goalscorer Alexandre Lacazette, with the French international at the top of Bilic's wish list.
The 24-year-old striker hit 23 goals for Lyon this season, building on his 53 goals in the previous two seasons for the Ligue 1 giants.
A ten-cap French international, Lacazette has become one of Europe's top strikers, and playing alongside his international team-mate Dimitri Payet at West Ham could be appealing.
However, Lyon have allegedly rejected that £31m, which would have shattered the Hammers' £15m record transfer fee, spent on Andy Carroll back in 2013.
Whether West Ham go back with another offer remains to be seen, but having failed with £31m, it's tough to see them increasing that offer.
