I was told ref blew whistle before Mina's header went in, hence not a VAR issue. But whatever the whistle was for was not for a foul that interfered with play in my opinion and I saw the ref ignore numerous niggling fouls off the ball by West ham on Everton forwards throughout the match - and I think VAR would have confirmed Mina's header should have been a goal. Also VAR, if it had been used, would have confirmed the corner West Ham were given was false: Sidibe was fouled and it should have been an Everton free-kick... thankfully Pickford stopped the shot that came from that false corner. Ref had a 'mare but overall the win was justified thanks to the team's 90 minute commitment and concentration.
