It was silly to take him for Mata when his influence was growing on the game. Ben Thornley even mentioned that on commentary for MUTV.
Bruno should've been replaced for Mata imo.
I thought subbing off was right to do. The yellow he picked up was petulant and could easily have been a red for the foul followed up with the shoulder barge. Completely unnecessary.
I personally think he looks out of control and if the media is to be believed Rangnick has already warned him about this.
There probably is some youthful exburence to be worked through and stars like Scholes and Rooney came with a bite, but football is even less forgiving now. The game isn't as physically aggressive as it was.
What I didn't agree with was bringing on Mata. The game lacked tempo. Palace were not parking the bus, they were attacking, playing the channels. We needed energy. It wasn't the game for Mata. The problem is who was it for?
We lacked a bench capable of bringing control with tempo into the game. This said I would have chosen Savage over Mata. He might not have the nouse or control of Mata, but he has the energy to replace Hannibal and as a natural ball player could have finally given us a clue in the midfield without suffering the lack of energy.
Not hard to see why the experienced safe Mata was chosen, but I just don't think it was the right game.
