1. EV played Roberto as a RB pick no1.
Reports say that Roberto will move to midfield.
So, something is off in this story since we are moving away from our RB pick No1.
2. the new kid has zero experience.
So, I don't believe that he will play anytime soon.
3. EV rotated Roberto and Semedo all the time, and when we had, for example, only Roberto, he was tired later in the season.
This would mean that EV will rotate Semedo and Wague.
Back to a point no2 where this kid needs tons of learning, adjusting and experience, it means that something is "off" again.
4. we have just bought Vidal, which means less time for Roberto as a midfielder.
So, my bet:
Roberto and Semedo will again play 50:50 of matches as a RB.
There is a tiny chance of Roberto playing some matches as a midfielder, if we'll have lots of injuries or if Roberto will play like a GOAT in midfield for some reason.
But not too likely.
So, Roberto and Semedo as fullbacks, and this guy is just another low risk lottery ticket for a distant future.
