I think we should give the Williams/Mori partnership some time. Centre halves need to play alongside the same partner for a while to see what they're really made of. Even the best centre-half in the world could look poor with a brand new partner every game
Mori is just an utter donkey. I can only imagine Ronny looks at him in disgust daily.
He can defend tho, just whether we wanna put up with his wild swipes at times.
