Allardyces future remains uncertain as he goes into Saturdays match with struggling club Sunderland . West Ham co-oweners Gold right and Sullivan left look on during a Premier League match . Win all nine, Im doing great. Lose all nine, get rid of him, he said. Thats a bit of tongue in cheek, but its true. Everybody would go away and say what a bad season its been. If we turn it around, what a great season. I dont have to defend myself to the owners. We all know in terms of where we are. Im disappointed. The players are disappointed. David Sullivan and David Gold are very disappointed in the run weve had up to now. At the end of the day were still 10th. Weve still got 39 points. Weve still got nine games to go. Anything less than 10th is going to end up being hugely disappointing, and around eighth is massive progress for us. Anything more than that would be a massive over-achievement for this squad. Allardyce confirmed he will be without James Tomkins for the remainder of the season after the defender needed surgery on a dislocated shoulder suffered in training.
