Yes they have a lot of players and have also brought in some good names too. Imo Chelsea will make the UCL. I’m so sure of this but they won’t win the league. They don’t have European distractions. Pochettino have given them a sense of play and they’re bonding and finding the rhythm this preseason. They will make the CL, people are underestimating what being totally out of Europe brings in term of squad's fitness. It's three teams that one can boldly say are ahead of them.
Chelsea need time to prove their strength in the Premier League next season. This sort of thing had happened before to Manchester United when they were really not in a strong form in the Premier League and things changed when Manchester United appointed Erik Ten Hag to be their coach the previous season. Well, it seems that Chelsea is currently feeling this because they have pretty good quality players but they haven't found a coach who can awaken their strengths. Pochettino is expected to bring Chelsea back to competing in the top 4 next season.
In this season Chelsea made many big changes, especially in this transfer window where Chelsea sold many players who performed poorly in the previous season and gave a lot of assumptions that Chelsea will start a new era with Pochettino next season.
