Paul Cook, Wigan's manager, said the defining point of the game was Arthur Masuaku's sending off. It was about all he got wrong the whole afternoon.
The defining moment came before a ball had been kicked. Around 1.30pm last Thursday when West Ham manager David Moyes turned his attention to Wigan's FA Cup win in 2013.
'If you went back and asked the Wigan people what they'd rather have,' he said. 'They'd rather not win the FA Cup, but stay in the Premier League.'
At that moment, West Ham's race was run.
