Sorry long time without coming here. Yes since last Confederations Cup he is a starter for our NT, doesn't look to me he is going to loose his place in the first 11 just because he isn't an absolute starter at City.
Regarding Gelson they do play in the same position in the NT but they are completely different, Bernardo was always a so called number 10 in Benfica youth teams who happened to be turned into a false winger by Jardim at Monaco.
While Gelson is more like a old school classical winger who likes to go very much in 1vs1, but imo his manager is pushing him too much in the physical side, I think he should be rested more, and sometimes he runs too much and should pause more.
Beside those 2 we also have now Guedes, our main problem is always the same, strikers and now centerbacks.
But yes, I like Bernardo and would like to see him starting for us next WC, even if I am not that optimistic with our prospects there, but that is another subject.
