Todd Boehly certainly really hopes that the appointment of Pochettino as Chelsea coach will give what is expected because last season they experienced something very uncomfortable. But we'll see that Arsenal need a few seasons before they perform well again as well as Manchester United so it's very possible that Chelsea will also need time to be able to impress again, even though in the pre-season match Pochettino said he was happy with the progress of his team but matches in the league will put a different pressure so results can be achieved very different.
Chelsea played against Dortmund and the Chelsea players showed that they have become a more confident team. Nkunku was subbed off early in the game after he appeared to have had a contact injury, it made Chelsea supporters a bit scared that he may be out for some weeks, but later on while the game was on, he walked back to the field unassisted which was a good sign that the injury was not too serious. Mudryk is a player to watch out for next season, he looks to be more relaxed, and his pace is back. Chelsea will make Todd Boehly smile next season.
Mauricio Pochettino has shown that he has all it takes to bring Chelsea back to their best and I'm very happy to see that happen. Despite the fact that a lot of Chelsea players who were part of the squad last season left the club, Chelsea are now playing more like a team than they did they whole of last season.
Though it's still preseason games which aren't seriously contested matches but looking at the current Chelsea style of play, one can say that they'll be a threat to other English Premier League clubs next season
