How many matches of Barca and Madrid have you guyz watched? I have watched enough of Barca and Umtiti to safely say he is overrated.
Can you guyz say how many matches of De Ligt, Otamendi, Skriniar, Vertonghen, Pavard, Salif Sane, Koulibaly, Tarkowski, Ramos have you guyz watched respectively to form opinion that they are not as good as Umtiti?
Looks like you guyz have too much liking for flavor of a season. why do you think Varane has much more international caps than Umtiti? Why do you think Umtiti has not scored any goals this season (not that i am judging him for that, but it shows he is not the strongest in air).
I already told the likes of Skriniar, Godin, Otamendi, De Ligt, Vertonghen all have better season than him and there are a lot more. I am just suggesting there are CBs who are better than him and we should pick one of those based on age/transfer fee/wages and most importantly natural defending abilities. Playing for barca mask a lot of defensive frailities.
Regarding bringing players from smaller leagues, its not a problem as long as you identify the correct ability. Umtiti himself was brought to Barca from Ligue 1, the league which might be just above De Ligt's Eridivise. Have you heard of Frank De Boer and Ronald Koeman? Our own Vidic was from RUssian league, for example.
If your answer is to again just talk some bullocks without having any backing, then you need not answer.
