Coutinho, like the rest of us, is just going to have to be patient. He's a great player but he's not Gerrard and can't drag us single handedly anywhere. He has to wait for Ibe, Can, Origi, Markovic, Ings, Kent, Wilson and Ojo to develop, for Firmino to adapt and wait for Klopp to work his transfer magic and undo our previous failures.
It's too much for him to overcome, but he's still young and can still win a lot with us. Patience is key here, he has to keep his head down and keep working the success he craves for himself and this club will naturally spring up in time.
