Too this Cucrella feature of a thing in the defense line had lapses and isn't working out for him, he should stop featuring him in that wing. Chelsea loosing 4-1 against Brightonham is a huge margin lose for a team like Chelsea.
That Cucurella idea and playing position is not working for Graham Potter, he should find a way to change his wing or change the player. Cucurella exposes Chelsea defence to dangers. He did it in their last match against Manchester United and discover the lapses and substituted him for Covasic around 36mins. Again today he was also weak which exposed Silva to too many pressure. Another thing I saw was playing Loftux over Chilwell. I don't think that it is a great idea. If he can consider to start every match with Aubameyang, it will give him more chances of scoring goals.
