Kamaldeen needs to realise that yes, he’s a good player at this level, but really not so good that he can do what the hell he likes.
If that really was Kamaldeen sulking his way down the tunnel then it's absolutely ridiculous from him.
I still don't get the expectation the ball will be put out if you sit down in the middle of the pitch. Let trainers run on like in rugby and very soon nobody will be rolling on the floor.
