Casemiro looked leggy, his passing was off and his decision making was troubling for an experienced player. However, the set up of the team did not help him one bit. It was obvious last season that Casemiro needed real legs next to him.
There were times last year when Casemiro and Eriksen were bullied. The remedy for that was to get someone with Fred's energy but something closer to Eriksen's passing. Not to buy another flighty, attacking midfielder like Mount. Mount is basically a younger, more energetic, less silky version of Eriksen.
You see Arsenal go out and get Rice to go next to Partey, you see Chelsea buying pace and power aplenty, Liverpool trying...Why are we trying to do the opposite? Even City are bringing centre backs into midfield these days.
Casemiro will be looking like Fabinho fast if we don't protect him.
