I'd expect Vinnie and Kun to be back, De Bruyne will have had 2 weeks off and Silva will have had a week in training to get him in better shape.

I think we need to play 3 in midfield, I don't think Nando should play so I think Yaya needs to play that role, filling in as a 3rd CB in a deeper defensive line, and spreading the ball on the counter to Silva/Sterling, with either Dinho or Delph making up the 4th runner.
Sevilla away style for me, sit and then counter, difficult to leave KDB out but I just feel Sterling's pace at a weak Arse backline, and Silva's possession is what we need, De Bruyne can give the ball away far too easily and we need to keep it tight, not give the Arse midfielders the ball back repeatedly. AK in because Clichy doesn't defend properly either, and AK's set pieces and crosses could just lead to a chance that Clichy wouldn't provide. He gets first pick when Clichy is the way he is.
