With the main knock on his time at Utd being his **** poor attitude, I'd think he'd be the last player Klopp would want to deal with.
Maybe this is to stoke up the chances of him being sold - but this is what Mourinho said of him -
"He's a very good professional, is the only thing I can say. I know the public image is always influenced by some details of their private lives but the reality is that he is a very good professional, a very good boy."
"He has a high level of education, super polite, super professional, and works really hard."
"But it's a position where I have Martial, Mkhitaryan, Mata, Lingard, plus Rooney and Rashford who can also play in this position."
"So we have six, seven players. When I have the feeling and information that the player probably has a big chance to leave then I have to care more about the others."
"But if you arrive in January and nothing happens - and we have lots of matches - then if he is going to be my player until the end of the season I will help him and he will be useful for us."
(This was before he was sold but wanted to go)
