If Kompany is back, I would rest Otamendi with that yellow card in mind. One more and he misses Leicester and we can't lose that game.
It will take Kompany and Aguero a while to be their normal selves, but should inject a good deal of confidence into the City team having them line up together.
--------------------Hart
Sagna----Kompany---Mangala---Clichy
--Fernandinho--De Bruyne--Delph
--------Silva---Aguero----Sterling
De Bruyne passes it as well as Toure, and is more mobile so I'd play him where Toure has been playing, and bring on Toure with 30 mins to go.
Use Navas/Bony off the bench and maybe a defender if Kompany is only good for an hour
