Maguire was very much moving out to cover WIlliams, he started moving in again and was caught out of position so yes, at fault. AWB was slightly behind DejOng and had the wrong body position, stopped movign when he should have tried to put him off and at fault yes. But Lindelof had absolutely no need to cover Maguire space that is absolutely rubbish, there was ONE player anywhere near him, behind him and he didnt watch him at all once he was in the box, just moved towards the near post, absolutely diaboilical and its hardly the first time he has been caught out this season from crosses.
Wy on earth are you going on about players having to step forward to cover space of other players when there is ONE player to recieve the cross who is directly behind him, your talking rubbish you dont hav eto cover spaces of other players when there is one player anywhere near the ball in the box, you have to cover the opposing player, that is it, he is the only danger, so mentiining under 10s as some kind of condescending argument, maybe you never got further than that level then if I can be condescendign back, absolute rubbish you are talking
