Slaven Bilic has seemingly started a mind games war with Jose Mourinho ahead of the two games at Manchester United.
The Hammers boss has always given the self proclaimed Special One his due and did so again in his press conference ahead of the League game.
But there was an edge to his comments as he praised him before reminding him of a less than expected season this time around.
Slav said: “Jose Mourinho is one of the greatest. “Statistically at home, there is probably no one better. But it’s hard to stay at that standard and maybe that has dropped now.
“I’m confident, if we can cut out the mistakes, and with a bit of luck, we can pick up a result on Sunday.”
Mourinho will want to improve on last season’s results against when United won only once in four outings and given his temperament may well be left stung by Slav’s comments.
