Allardyce believes the Hammers, currently 12th in the table, would be finishing the season in the top half had Andy Carroll been fit and insists the club need to bolster their attacking options in the summer.
"What we need to do is find an alternative type of front man that scores a few more goals, we'll have to do that," Allardyce said.
"If Andy had been with us all season, we'd be top half, I'm convinced about that.
"Carlton Cole has done a fantastic job but it took him a long time to get going because he didn't join us until after the January window had shut, and Modibo Maiga has struggled since he's been here unfortunately. We would have hoped he'd have done better.
"I'm convinced the front man is the key to how you do in a season, and if we had Andy out on the pitch, match-fit and scoring the goals we know he can with Kevin Nolan, I think we'd be a lot further up the table than we are now."
