Whilst I agree with your comment about Carrick's forward passing, I must say do we really need it now? In past seasons we've had a midfield devoid of players who can move the ball forward so relying on Carrick spraying balls out wide and in between the lines was a must, however now I feel we have a group of players who can move up and down the pitch fluidly, and as good as Carrick's vision, passing and ability to slow down and speed up the game is, he isn't as mobile as Fellaini, nor does he often link up play higher up in the field.
Although, Scholes and Keane is a similar matchup to Carrick and Pogba, in terms of players, so who knows? I do think we'll be in for a 'surprise' with how much game-time Fellaini gets this season, but is it really a surpirse anymore cos he sure isn't as bad as many make him out to be.
