Butland's older and made more mistakes than Karius this season. He's also not suited to our style of play. Butland is your typical old fashioned keeper, hangs back on his line - we need a keeper that sweeps up behind our back 4 and is comfortable playing out from the back. I don't think it's any coincidence that we brought Karius into the side the second we signed VVD - signing VVD meant we could play a higher line which meant we needed a keeper that could cover the space behind the back 4. Karius done that, Mignolet didn't and Butland won't. If we're choosing between Butland and Karius then I'd stick with Karius.
Not sure what Allison done wrong in the games against us. I can think of a fumble from 1 corner in the first leg but other than that I can't remember too many mistakes - he certainly couldn't be held responsible for any of the goals. I think Roma have priced him out of a move after we had their pants down for Salah though.
