I'm not convinced he's much better than Ospina tbh. The main attribute he came here with was his so called elite level of playing it out from the back. Maybe he was a big shot at playing it out around Norwegian pig farmers in the German league but i've never been impressed with him doing it here. They'll be debating for some time about wether we should have sold Martiniez or him last summer. But one thing is for sure, Martiniez ability at playing it out from the back was light years ahead of him, they're not close ability wise.
