Yaya needs a rest, this should be part of a planned phasing out of the once great Yaya, or at least scribble out that "must play every game" clause in his contract, which just wastes his talent by wearing him out.
Silva being back is a great plus, if we can get the penetration down the flanks, and Bony shifts his arse into the box, we might should Stoke over. the midfield enforcers of Delph and Dinho will make us solid in the middle, hope Nacho gets some game time too
