You think Chelsea problem is between the management and not the players? I think this is the first time I have seen owner of a club so serious about his club since I have known Chelsea, the previous CEOs are always underground doing their other business and running the club concurrently but Todd Boehly is a serious business man. What I think they lack is real Manager that can handle the teams properly, the ones they have hired so far are quack and not professional and that mistake started since when they let go of Tuchel for political reason within the stakeholders.
What they need right now is new person that can coach those guys property, Pochettino is just there to amass his weekly payment, when the time is real and Chelsea want to do the right thing, I believe they will let him go and look for another person that will give the team the appropriate ingredients needed to make the team stand and looks strong with a good striker that will be giving them a lightening speed and goals.
I believe you because Chelsea signed new players and they are good players, it is just that the manager is not good enough to control the players as they should be, I am very sure if Tuchel is still in the club i don't think Chelsea will be very bad like this, because Tuchel is very experienced coach and very talented, I don't know why they sake him because he just lost form once, They need to give him time, because when Chelsea play against Real Madrid in the Champions League final in 2021 and defeat Real Madrid and Manchester City in the final, that is when I started respecting Tuchel, because that season's performance was very brilliant and any club would like to have him, and now he is performing in Bayern Munich and I am very sure he will try his best and win the Bundesliga trophy with them, possibly even the Champions League, but he won't be easy sin. If Chelsea gets a better manager, they will be able to play well and qualify for the Europa League next season, they need to qualify for one competition.
Arsenal are wobbling right now, but it is different from what happened last season, then it was so close to the end of the season, this time around the season is just midway through, so Arsenal has quite a lot of time to get back to their best form and challenge for the title. If you look at the league table, you'd see that there are so many teams in and around the summit and the points difference is not so much, just 6 points separates the top 5, thus nothing is either lost or won at this stage.
Arsenal still has a chance to top the league table if they perform well in their remaining matches, because I believe Liverpool will draw or lose some of their remaining games, and if Arsenal can compete with the other big clubs in the league and win them, I believe they can top the league again. I don't think Aston Villa will finish in the top four in the league table because I believe Liverpool, Manchester City, Arsenal, and Tottenham will finish in that top four. Aston Villa will definitely fall when they start playing with big clubs, because even Manchester United, who are not in good form defeated them. Arteta need to wakeup and win the league title this season because they deserve to win it these season, is long now that they won the Premier League trophy.
