It is obvious that Semedo has changed as of lately. He is better defensively, makes fast drills from the flank and does cover for G.Pique when the last is at the opponents penalty box !!!
Semedo is a placeholder at best. He should be so much better, he has the pace and technical ability, but somehow hes not as good as he should be. If you watch Alphonso Davies for example and compare them you might want to cry. And he has no apparent leadership qualities either. The Lenglet of fullbacks.
If we can struck a deal with Betis for Emerson and use the cash from Semedo for Upamecaono*, Ferran Torres or a player like Camavinga we are so much better off.
Cancelo isn't known for his defense at all. Going to be interesting to watch our right side with Messi not tracking back, slow midfielders like Busquets, and slow CBs.
I don't like Semedo and I think he is the most overrated player in our current squad (by Barca fans at least) but Cancelo is just even worse option.
He isn't really a fighter and can be the worst defensive option you have for a full back
I think Semedo is not overrated and is a top RB in a period where outside Alexander Arnold nobody is that great as to be a clear improvement over Nelson.
In other words, we should stop worrying about positions which are filled with top young players. Not with the situations in the winger positions, at no9 or even in central defense.
