Graham Potter has adopted some mannerisms coined by previous Chelsea managers already. They are most likely simple accidents, but listening to the 47-year-old call Edouard Mendy 'Edou' and N'Golo Kante 'NG' might have helped Chelsea fans get over Thomas Tuchel slightly quicker.
Not too much has changed about Chelsea in the meantime. They have become defensively sound - though Kepa Arrizabalaga was a big part of that against Aston Villa - and have found an attacking spark once more. The three man defence is playing well, whilst changes in formation have become a staple. It's Tuchel's takeover 2.0.
An outsider would be excused for not telling the differences by and large between Potter's Chelsea and Tuchel's. The differences are subtle and important, though. Whereby the German was outwardly aggressive and demanding of his players, Potter cuts a suave figure on the touchline. Closer to Carlo Ancelotti than Jose Mourinho or Antonio Conte.
