Crystal Palace claimed their first win at the London Stadium after a 2-1 triumph over West Ham United.
Striker Sebastien Haller had given West Ham the lead nine minutes into the second half.
But Patrick Van Aanholt equalised for Palace with a penalty on 64 minutes after Declan Rice had handled in the box.
And with three minutes to go, Jordan Ayew swept home a VAR-assisted winner after his initial effort was ruled out.
