West Ham boss Slaven Bilic has pleaded with fans to lay off the boos.
It comes after a double substitution against Swansea before the international break was met by a chorus of jeers at the London Stadium.
Bilic said: "It's better to be clapped than booed.
"But at the end of the day I have to trust my decisions. Those decisions gave us what we wanted.
"But it doesn't have to be that the next time we will do the same decision. The fans were not happy with my decisions (to take Hernandez and Ayew off) but they were really good."
