The Hammers co-chairman says a 20-goal striker would have seen their season end very differently.
West Ham United co-chairman David Sullivan has told the club's official website that their season would have gone very differently if they had had a 20-goal-a-season striker at their disposal, and admitted that he will not rest easy until he has brought in a player of that calibre this summer.
The Hammers threatened to gatecrash the Premier League top four for the first time this season before ultimately falling away to finish in seventh place.
That was still their highest finish in 14 years, and was built largely on the success of summer signings such as Dimitri Payet, who finished as the club's top goalscorer with 12 strikes from midfield.
However, the Hammers top-scoring striker, Andy Carroll, hit just nine goals and the only two other forwards still at the club, Diafra Sakho and Enner Valencia, netted just nine league goals between them.
Sullivan acknowledges that this is a real issue for the club, suggesting that their season would have ended differently if they had had a more prolific marksman, and admitted that he will feel a lot more confident about their squad once they have brought in a top-class striker.
The co-owner told the club's website: "Once we sign a top striker I will feel a lot better and that is the main position we need.
"Our top goalscorer last season scored 12 goals and if someone had scored 20 we would have been in a different position."
The Hammers have already begun their search for a frontman, with players such as Lyon hitman Alexandre Lacazette widely linked in recent weeks.
