Graham Potter is still acclimatising to life as Chelsea boss having taken charge shortly before the international break.
The former Brighton and Hove Albion coach was hired as Thomas Tuchel's replacement and is getting to grips with his new squad having had little time to work with them or see them in action. A behind-closed-doors friendly against his old employers gave him a chance to do so, with potential new ideas trialed.
Potter is working with a lavishly assembled squad that was put together in the summer at huge expense. Huge fees were spent on the likes of Wesley Fofan and Raheem Sterling as the Blues look to get back to winning silverware under their new owners.
