Whilst I hope we rest some players playing a true reserve side and or kids and getting hammered 7-0 won't do us any good even if it is an effectively meaningless game. I'd play 4-5-1 with Fernandinho, Milner and Garcia in the middle, Navas and one of Silva/Nasri wide and start with Dzeko up front but give Negredo half an hour. Try to stifle them, really get in their faces and maybe nick it 1-0 or hold them to a draw, worst case lose by a couple of goals.
