Andre Gomes was impressive at times against Barca. He's got great technique and is very strong and physical 1 vs 1.
One thing, I knew he lacked pace but against Barca where they played solely on the counter he looked very, very slow. He couldn't push the ball because Barca players caught up with him rather easily. He passed it rather early for that reason and it broke their momentum at times. Good performance overall anyways. Mustafi was a gladiator though, he had Suarez in his back pocket.
