Obviously, Chelsea can't finish in the top 4 in the upcoming season. It's too good to be true. I think Chelsea will fight against relegation, not for a top 4 spot. The pre-game result is enough to judge Chelsea's EPL performance soon.
Chelsea was losing Silva, then this time Gallagher. Almost no experienced players in the club so far. It's also very obvious Chelsea is not even ready to face the pressure in the EPL soon.
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.
