Horrible defending, should never be ahead of Semedo, defending in the penalty box with 10 feet away from the attacker
Said it before, but he's too passive. He knows he's slow, knows he can't tackle, so is reluctant to commit and offers far too much space to the opponent. And I know it's unfair to compare to Alba because Alba is, well, a lot better, but Alba picks out the right ball in the box pretty regularly - honestly can't even remember the last time Roberto found anyone in the opposing penalty area, let alone the right person.
you could have a prime dani alves on rb, and it wont matter if the player does not have support.
in the 4-3-3 dani alves had xavi as his backup
in 4-4-2 / 4/-2-3-1 our rightback needs support from the RM, Alba gets a lot of support from Coutinho / Iniesta the defensive mids have to cover the box more than wings, only one that can be blamed here is dembele looking back at the replay sergi roberto could do almost nothing against the assist in the first goal.
