The striker was released before being re-signed by West Ham last year.
He told whufc.com: "We're going to start next season with at least two fit strikers. Obviously we need reinforcements and we've got Modibo coming back as well, so we'll see how that goes with everyone getting a good pre-season under their belts and trying to perform to the best of their abilities.
"We should be, from an attacking point of view, all guns blazing. We've got to play to the manager's style of play and capitalise on any challenges he puts in front of us. If we get things right before then and the preparation that should be good, hopefully we can do better next season."
