I think the problem that I'm sure Millwall fans see is that yes the man is standing in an offside position but has him being them stopped the GK from seeing the ball the whole way. He appears to see the ball the whole way and saves it . He then spills it which isn't because off the Millwall player being there and then the other player taps home. I guess it depends which side you are on but Millwall were certainly on the wrong side of alot of decisions this afternoon. There were a lot of other decisions during the game that were very inconsistent. I feel too many soft fouls were given and he could've allowed more physicality to go in a game that was very feisty and competitive
