The former Toffees boss sent his side out very much on the front foot in pursuit of Champions League football at Burnley on Monday.
A 2-1 win – a scoreline which flattered the Clarets – vindicated his approach, but Moyes must balance whether Everton and Carlo Ancelotti will allow the Hammers to be quite so open on Sunday.
Moyes knows top-four rivals Chelsea – who are currently three points clear – will do well to maintain that margin as they visit Manchester City and there is a sense that every chance must be taken.
Moyes hinted in his press conference that he may rotate the starting XI, which could be bad news for Said Benrahma despite a dazzling display against Burnley.
“I always feel we have players, and we’re starting to get some of them back, that we’ve got more options than we had,” said Moyes.
“It was great we got Said in a position to contribute, Jarrod Bowen is scoring goals, three in five, but we need to keep the options and flexibility of the front players. I want to rotate them at times and I want to make the right choices.
“Fortunately it worked and we got a good result.”
Moyes was coy over whether Declan Rice could return from injury. Angelo Ogbonna was hopeful he would be able to return from a hamstring problem against Everton, though Moyes has not confirmed his availability.
