Agree, just to add some more. Mata knows his limitations though, so he release the ball very quickly, pressing him is pointless. One of the traits which makes Mata our best player in inter-change movements, linking attacks, and transitioning possession upfield. Very rarely he hold the ball for far too long. Downside, too many safe passes than few riskier killer passes. Not a problem since we now have Sanchez to balance it.
Mata is bad at holding the ball though, can be dispossessed easily, hence why he rarely does it. Matic and Valencia are awesome at holding and keeping it. Pogba lose balance and ask for a foul too much though, despite his actual top class capability at that. Martial is not that bad, but must face defenders instead of backing them up. Valencia is better when facing than backing, so I would say Matic is the best one at both. A must have trait is composure and calmness.
