Total lack of communication between some of our players.
At one corner Grujic was begging ( I think Patterson) to tell him where to go and who to mark.
Millwall had. Virtual free header.
When Millwall hit the bar Bamba and Grujic had a man each, but Bamba didn't take responsibility and assign Grujic to his man. They both ended up a yard off their man.
These are basics.
Manga was yards off Gregory for their goal - marking fresh air until he saw the danger too late.
Is maybe Grujic's English not that good perhaps ?
