West Ham co-owner David Sullivan admits Sam Allardyce never suited the club.

Sullivan says the board is delighted with the impact of Slaven Bilic this season.

"Judge every manager over three years but I think we have got a very good one," Sullivan told the Daily Mail. "He played for the club, knows what the supporters want, knows that the FA Cup is important to us. He tries to play good football.

"Yes, it's possible that we could review his contract and do something in the summer. But it's more likely that we would do it next January. You do get one-season wonders, after all.

"Unfortunately with Sam, although he did a good job, the supporters never warmed to him. Nobody ever sang his name. Maybe 'cos Sam swaggered a bit. Maybe it didn't help.

"When we were booed off after winning, it was the weirdest thing. I felt the same. That's one of the reasons we knew we had to make a change. Sam had done his job well and we thanked him for doing it.

"But, physically, he was tired. He needed three months off and he has had it and come back like a tiger as we all knew he would. With luck he will keep Sunderland up.

"He is a good manager but he does it his way and at West Ham we do it our way. Sam never really bought into that. West Ham fans want a dream, they don't want reality."
