all two of them?

Costa can rotate upfront as an SS, Cuads can compete for the RCM/RB position. But I agree with the critics of this formation, neither our RB or midfield are good enough for this. our midfield personnel at this moment is hardly sufficient enough for a midfield duo with Pjanič, Khedira and Marchisio injured, if we ever reach a point this season where at least 4 of our reliable midfielders are available and in some kind of decent form we can start considering a midfield trio.
