Rakitic was the same shit. In fact, Rakitic was clearly worse in the build up while being the same defensive liability as Busi.
While Busi wasn't missed because his level has been bad, playing Rakitic is not the solution. The ideal situation should be with FdJ as the starter and Busi as his sub, or if Valverde doesn't have the balls to bench Busi, then Frenkie should always be used as the cdm in his absence. Not Rakitic, since we're just exchanging a bad player with an even worse one in that position.
It's like saying Alba's absence wasn't an issue because we won last night. It completely misses the point.
