Only other CB we had on the bench was a 16 year old. Montano could've filled in there if he didn't also go off. Mo in general tends to just stagger around the place when not concussed to be fair. He was a CM filling in at CB as well.
I was more surprised as Sangare, our CB, burst into the box with a late run while we're clinging to a 2-1 lead. A proper box to box centre back performance from him today.
