Fair point. But the likes of Carrick and Blind would've helped us keep possession better, preventing Leicester launching attacks as frequently. Once the game went to 3-2, it was noticeable how little we retained the ball.
The other thing is that holding players tend to fill in for attacking full backs, and both Rafael and Rojo left a lot of space in behind at the weekend, leaving the CBs exposed.
For tougher assignments, having the extra insurance would be prudent. Against West Ham, for instance, I think Blind on his own will be fine. Against Everton the following weekend, I'd prefer an extra conservative midfielder in alongside him.
