Aggression is fine but you need to be calculated and tackle with the correct technique. Gavi many times this season has just ran at opponents and shoved them instead of making a proper challenge, or lunging in like today.
Aggression is fine but when you are not on form or fully fit then it will lead to outcomes as today.
JamDav made a good point. We're creeping to a territory where we have two many old legs and the team is caught in two minds. Obviously the seniors will hold the reigns on which direction takes over.
No suprise that our best games under Xavi have been with either Pique or Busquets. I fear for Alves when we play more than one game a week as our whole build up will turn to lethargy.
