At the moment Chelsea are still unbeaten after having Potter there and of course with their 3 wins to date they are back on a good run in the Premier League table.
Potter is usually smart with his selections. He made good selections for both PL game and CL game and won both the matches. Next they are up against Aston Villa and in my opinion they should be able to win that match. However in my opinion they are still far from their usual self and might struggle going against big sides.
