Our best defensive performances this season featured Sagna, Kompany, Mangala and Kolarov, so I'm surprised that he's left Mangala out. His extra pace could be important if Martial is playing and he and Kompany seemed to have developed a good understanding.
I'm also disappointed that Navas has been dropped in favour of Sterling. His work rate and ball retention is much better and he does create so much space for other players while Sterling tends to drift in.
Hopefully we'll still batter them but I'm less optimistic than before I saw the team sheet.
