I actually thought he was doing pretty well at Bayern but they gave up on him it seems.
He'd be our best winger immediately. If he was cheap we would be absolutely mad to say no so we can play Bernard or Iwobi every week.
Bayern reportedly have the option to sign Coutinho on a permanent contract in the summer of 2020 for €120 million.
Thats why they gave up on him.
And he wouldnt be cheap.
