Is his mother really always there with him? did not know that. Yes, he certainly needs to start living on his own now, he is what 21 or so? I think Morozov was good to be easy on him but this is not as easy sport and maybe he needs a Frank Carroll to push him a little but and tell him to cut out the drama.
He was 23 on March 25th, which, yes, is the age to leave your mum behind. Agreed for the rest of your post - Carroll could be a good choice. Not sure wether he would take him, though.
