West Ham boss Sam Allardyce bemoans managerial dismissals

Sam Allardyce says more and more managers are losing their jobs because of the need for instant success in football.

Allardyce takes his West Ham side to Chelsea on Sunday, looking to complete the double over the European champions after a 3-1 victory at Upton Park in December. The trip across London is just one of three fixtures for the Hammers in March due to their FA Cup elimination and the upcoming international week. "We knew the situation, we have managed situations like this at international times," said Allardyce. "All we can do is do what we did last time we played and try and win because then it makes the two weeks pretty pleasurable to handle it and get through it. "We have got exactly the same situation on Sunday when we have two weeks again before we play West Brom and we have got to try and handle it the best we can. "I would rather have played last weekend but I'm not sure about playing Thursday night and Sunday because that is the hardest thing to overcome. "Whether you have a good result or a bad result in Europe it is always very difficult to get the players to a top level of performance but Chelsea have been doing that for years now." West Ham will still be without skipper Kevin Nolan, midfielder Mark Noble and former Chelsea man Joe Cole.
