West Ham United boss Sam Allardyce has branded the sacking of Paolo di Canio at Sunderland as "crazy".

The north east club are currently bottom of the Premier League and have taken just one point from their opening five games.

Allardyce said: "They have been pretty quick in pulling the trigger with the last three managers. If it doesn't go well then they seem to make a knee jerk decision to change the manager.

"Steve (Bruce) and Martin (O'Neill) in their seasons had a bit longer but I find it very difficult to see where the logic lies in this when there has been a full clear-out of the backroom staff.

"To go through this when the season has just got underway is a huge task for whoever is going to be the new head coach in charge. From my experience they have got a massive job on their hands in who they select as the new manager.

"The new manager then has a massive job on his hand making sure he re-addresses the situation with Sunderland at the moment."
