I honestly think Aguero needs to be rested for this game, i think he is one bad fall or stretch from another injury- Nacho must start for me, even in the FA cup game when we played the kids (who were better than our senior players in that game) Nacho was one of our better players - we will need Aguero more in the games coming up, can still play a strong team without Aguero:
Hart
Zabba Komp Manga Clichy
Dinho Delph
KDB YAYA Nasri
Nacho
That leaves: Cab, Sagna, Ota, Kolarov, Fernando, Aguero, Silva (although i doubt he will not put Bony on the bench - but we can all live in hope)
This bench would leave lots of options Maybe even rest Sagna or Silva Completely and have navas or Garcia (or Bony :-( )
