Think it's better for him to play with barca b every week than riding the bench with the senior team.
I think i'm in the minority when I say that i was not that impressed by him. I couldn't watch the match live, but on the highlights he doesn't seem very athletic and seems to choose to play passes rather than attack the flank
So basically, you didn't like him because he's not a young version of Alba.
Well he made some nice big switches and played that nice ball in behind the defence, but the best FBs today are great attacking weapons like Marcelo, Alaba, Walker, Felipe Luis....
Have a look at minute 1:15. He could be more aggressive but plays safe passes.
I still advocate his being Alba's backup, though, instead of buying a Digne replacement.
He didn't put in a foot wrong. His long balls and switches were exactly what we needed almost every time he went for them. He didn't attack the defense the way you'd expect Alba to but that just meant he was in position to help our defense, which meant that not only was he creating chances on goal with his passing, but on our end we weren't threatened by Spurs at all.
If you're seriously not impressed by such a performance I really don't know what to say.
Good thing nobody's comparing him to Marcelo.
