West Ham United reserves boss Kevin Keen is convinced Bobby Zamora can fulfil his potential at Upton Park.

Fit-again Zamora struck a hat-trick in this week's 4-4 draw with Birmingham City and Keen told WHUTV: "Bobby is an outstanding athlete. In my opinion he is one of the best forwards in the Premier League when he is fit and I have told him that on many occasions. We have just got to be a bit careful as to when we bring him back.

"We haven't got a game this weekend and then we play Fulham away but he could be a real diamond to have in the run-in for Curbs and Mervyn. He can really turn games, he can score goals - I don't want to speak too highly of him because he is a big enough character anyway."
