The most concerning part of Sunday's defeat to Aston Villa for Graham Potter might have been the lack of maturity from the few senior players involved in a mostly academy-infused squad for the friendly in Abu Dhabi.
Marcus Bettinelli, Marc Cucurella, Jorginho and Pierre-Emerick Aubameyang were the oldest players selected.
Apart from Bettinelli, whose only appearance for Chelsea came at the very beginning of 2022 in the FA Cup against Chesterfield, the other three would be favourites to feature in Potter's first competitive line-up back against Bournemouth in two weeks' time. Potter, apart from needing some key players back fit from injury, requires his senior figures to offer composure and leadership in a challenging moment.
