Quite odd this player.
Occasionally he's brilliant like Alves was. Like that play when he dribbled 3-4 Bilbao players in short spaces. I mean, who does that at fullback these days other than Marcelo? But other times his confidence just fades away.
Imo, his mentality is not up there. Maybe he's not been integrated in the team the right way. Who knows. I wouldn't give up on him though.
As for this game, I was overall okay with it. Don't see the big fuss. Yea, he had 2-3 passes which could've been turnovers, but he pulled them off in the end even if not struck the right way. He was beaten by Kane, but Kane wasn't his man this game. It was more a play in which this player appeared in his zone, he had to cover in a short amount of time and was in a spot where he had to commit. Kane is world class and won that duel. But it's not actually a big mistake. Every time attacking players win some duels with defenders. Kane had won a very good position there because other players made mistakes too.
Son, who was his man was nullified by Semedo. Didn't do anything of note, and couldn't use his speed to get past players.
Problem with Semedo is that I'm still waiting for him to let loose and show the brilliant stuff he shows in glimpses, but it doesn't happen. Maybe he's one of those mentally frail players who have the tools as in the talent, and skill, but not the brain for the highest level. It kind of is known to affect portuguese players. Looks like the Quaresma of RBs Semedo at times. He pulls off some quite impressive bits of imaginative skills, but the consistency and mentality isn't there on a constant basis.
