He dint have a stellar performance, but we have a feeble squad as it is and this lad can be immense for us, given a chance and support. We will never win anything with a midfield combo of Hendo and Milner. Not in this century anyway.
... and that's why we bought Ketia, but what can you do if he's injured. The question is, is Fabhino better than Kann ? I don't think so.
As for the Arsenal game, Klopp could have took him off as we had the tools to win the game on the bench.
