I think it's far too early to say we don't miss any of those three players, but especially Fellaini. There will be times this season where we'll see Barry look his age, or indeed McCarthy look his age, and wonder what could have been if we had Fellaini.
And despite the start to his United career, Fellaini is one of their best midfield options and I have no doubt he'll come on leaps and bounds.
That said, £27.5m was good business obvious and I'm very happy with the increased balance in midfield thus far. For all Fellaini's talents, keeping the ball moving quickly wasn't one of them, so perhaps he would have been the square peg in the round hole at Everton under Martinez - we'll never know for sure.
Gareth Barry is the one that makes everything tick, so I hope everyone doesn't panic if we go to the Etihad and get stuffed without him because we're still a work in progress and that has to be remembered.
