Is it overkill?
Last season we saw an inexperienced Chalobah prone to errors at the latter end of the season.
We saw arguably the worst CB to ever put on a Chelsea kit in Sarr who was a calamity waiting to happen.
We saw Azpilicueta prone to errors towards the latter end of the season given he can't keep up with the pace of the game anymore.
We saw Alonso being Alonso whilst Chilwell was out of the esason.
We saw James overplayed and injury stricken.
For me, this has to happen.
