Wolverhampton Wanderers chairman Jeff Shi has criticised the referee's decision to deny his team a late equaliser in Saturday's defeat by West Ham United, saying the Premier League and referees' body must "uphold the integrity" of the league.

Wolves were left fuming when they thought they had made it 2-2 in stoppage time after Maximilian Kilman headed in from a corner before the goal was ruled out for offside.
