West Ham's O'Brien confident knee problems over
Former Bolton Wanderers ace O'Brien has impressed on his return to the Premier League this season.
He told whufc.com: "It is sorted. It has been a long time since the last operation on my knee and I think the main thing with long-term injuries is just about playing as many times as you can and keeping on the pitch and in the end the pain just goes. It is obviously something I still manage every day in training with the staff here, but it just great to be back and playing football again is amazing, it is great to be at the top again."
