I also think that Chelsea will still find it quite difficult to reach the top four next season with the current squad condition, but on the other hand I also don't think Chelsea will fight to avoid relegation because Chelsea will definitely be able to save themselves in the middle of the table like in the top ten or below next season. In addition, the Premier League which is still known for its strong competition from every opponent can also benefit a team like Chelsea because after all Chelsea is not the worst team in the Premier League.
It's hard to say what Chelsea are capable of with Maresca until the season starts, but I don't see how they can fight for the Champions League zone. The team has progressed with Pochettino, and if he had stayed as coach, I would have expected Chelsea to be able to do it, but Maresca is changing everything at his own discretion again and I can't imagine what Chelsea can be like, but for now I find it hard to believe that they will be able to fight with the teams from the top of the table.
