Chelsea has just changed their coach,I think we should give him some time before results will start to come.If these results do not start coming despite the new tactics that this coach will implement then there is only one possibility left for Chelsea to not lose a lot during this season and that time is the January window transfer,they should be very active and start since December if things do not go well during October (November is World Cup) and buy some good attackers where it looks like they are suffering the most.
Graham Potter needs time to get familiar with the players and knows how to use them on the pitch. The recent manager, Thomas Tuchel giving Chelsea the champions league is one great and memorable achievement in the club and would always be remembered. Talking about this new boss, He only have a draw in his first game, so let's not conclude yet about his tactics, because I'm aiming for more victories for the blues. Graham might not like some of the players but he will try to adapt and use them in games and then for his priority targets during the January transfer window.
If Chelsea judge Graham Potter better than Tuchel, then Graham Potter should be able to do it quickly. Because Tuchel at the time of his arrival the club situation was chaotic for the Premier League and also for the Champions League, but Tuchel was able to do his job quickly while at that time the rival teams were also at their best. So comparing Graham Potter to Tuchel for his first impressions at Chelsea is incomparable because after all, Tuchle can do it quickly to get the perfect result.
