Think Pep's tactics don't help attacking fullbacks at all. He seems more interested in them being extra CM's than overlapping and trying to actually join attacks. Perfect for Zinchenko, who wants to be doing that anyway, or Walker, who looks very happy passing it sideways, but for Cancelo, Angelino and Mendy it's cutting out the best aspects of their play. It's weird as at Barca he loved a rampaging rightback, but over here he seems to have become more interested in having extra midfielders at the expense of any width in the team
