It is not possible for Chelsea to win trophies this season because their squad are not very strong like some of the club we have. Arsenal have really in improved looking from their game in the preseason match , if time is not taking Arsenal may even take over the position of Liverpool in the next season. I'm not sure Liverpool will be strong like in the last season. The new season will be more competitive, teams like arsenal will be tough to challenge Manchester city and Liverpool.
Chelsea loss many player have been in the list for transfer because taken by Barcelona, but with few days later before league begin I think Chelsea could find new player. I think Chelsea looks not strong like last season but we can't make Chelsea not in the list for Primer League winner candidate for next season. Still have opportunity actually Chelsea have great mentality with Primer League, I think Chelsea need to completed their transfer window and get central forward early as most important thing because right now Chelsea don't have talented on central forward.
Yes, I also think that Chelsea are not strong for the new season because they have lost players and have not looked for replacements quickly. But even though Chelsea will not be in the title race for next season, I still believe that at least Chelsea can still compete for the top rank at least in the top 6. Regarding Arsenal, they got a change for the better if we consider from this pre-season game but unfortunately, Arsenal are not alone as a team that has made improvements because there are other teams like Manchester United for example. So still, for two positions in 3 and 4 it will be a fierce competition for many teams because for 1 and 2 I believe Manchester City and Liverpool will still dominate.
