West Ham United manager Manuel Pellegrini has denied that Lucas Perez refused to come on as a substitute in Sunday's 3-1 win over Everton.

Perez was involved in a heated exchange on the bench while Marko Arnautovic was being replaced in the second-half.

This lead to speculation that Perez had refused to come on, but Pellegrini has denied the claim.

He said: "When Marko was injured, I called for Lucas because he had been warming up, but when I saw he was sitting on the bench because he had finished and Antonio was working, I saw that Antonio was ready.

"That's why I changed path and went with Antonio, and not wait for Lucas to warm up, because we needed to make the change immediately."
