Teams are figuring out they can put pressure on him and he can't wiggle his out of it due to age/worse technical ability and vision that Cubarsi. In this bad run of games, he was the one frequently giving the ball away or choosing the bad/safe pass to Balde that trapped him under a press.
I think when Casado drops back to form a back 3, Inigo's pace/poor dribbling prevent him from progressing with the ball up the field. Bad as Araujo is on the ball, he can definitely bomb forward, so I'm looking forward to what he looks like
