The wheel hasn't been reinvented, Graham Potter is working with the same players Thomas Tuchel was and his struggles may well be similar.
It's too soon to draw effective conclusions from Potter, especially as it has only been eight games, but also because it was all looking up before the last week where an old head reared itself at the worst time. Chelsea are still unbeaten though and in a promising position, but you perhaps wouldn't have thought that was the case such has been the reaction to back-to-back draws.
In context, Chelsea drew the final of three away games after taking maximum points before that on the road and then fell foul to a last minute equaliser against Manchester United. Not the worst going but made more frustrating by Arsenal and Tottenham also dropping points over the week.
