He was at fault in both goals. First more so, but shared blame with Samu for losing the ball, Romagnoli for not actually moving, and Calabria also ball-watching with Kalulu when Donna saved the first shot. Second was just unlucky losing an aerial duel from a good cross - happens.
But, regardless, he didn't seem to let that affect him. It's a good sign, he wanted to keep going as MB said, he wanted to play and try to come back - and he did it. He scored. He was in the right place and pounced on the ball. A point was an unacceptable result, and conceding two goals fucking sucked the way it happened that Kalulu was at fault for both in some regard but everything bar those two instances he was good. I'm still not sure if he should be played as a CB going forward. With his passing and pace, I'd think he's better suited as a RB since his defending isn't actually bad at all, or even converted to DM.
