He'll be a huge boost now that he's finally back. Does so much defensive work that goes unnoticed, and helps control games. Nobody in our team has the ability to dictate games like he does either. The way Van Gaal talked about him in the pressers makes me think he rates him really highly and him being out was a huge loss. Now that he finally has midfield partners able to create and do defensive work like Blind and Herrera, players willing to go deep and pick up the ball, and energetic players, he has every chance to go back to his best. The only problem is the age but given Herrera and Blinds mobility, I think it'll prolong Carricks career.
Put him at the base of the diamond, Blind on the left and Herrera on the right, Di maria at a free role in the middle and that will IMO be our go to lineup in big games where we need more defensive cover. Seems like the Chelsea game will come too soon for him to start, but hopefully the City game a week later we can do something like this:
De Gea
Rafael Jones Rojo Shaw
Carrick
Herrera Blind
Di Maria
Rooney Falcao
Just a great mix of passing, control, defensive workrate and players shielding the defence, and creativity and pace going forward. No players there who don't do their share of defensive work or pressing, and all very capable on the ball. In smaller games we can expect to dominate we can put him at center back next to Rojo/Jones or simply rest him to accommodate Mata/RvP.
