But former Hammers defender Tony Gale told the Sunday Mirror: "There isn't another striker like him at the club. To have him back will be a big plus.
"He has developed into someone who, I am convinced, is the best English front man of his type in the Premier League.
"He gives the team talent and a great physical presence. We are seeing the best of him now.
"He has settled down now with a family and anyone can see the effect it has had on him. It has been very positive.
"If he continues to play like he has so far this season, I see the perfect front-line partner for Wayne Rooney in the World Cup finals. As long as he is fit, he is the man for that job."
