Your wish seems unreal after Chelsea's horrific performance against Manchester City's young squad. I'd rather take 10th as the possible for Chelsea to finish in the current season.
Smile, you want Chelsea to stay in their favorite spot next season. Chelsea's performance against Manchester City was poor, the attackers did well, but the defense was very weak, if a team concedes more than it scores, it's absolutely nothing because they can't get any points in their games. So, despite all of the players Chelsea has signed, they can still concede many goals in their games. If Chelsea continues to perform like this next season, they cannot finish among the top four Premier League teams.
Joshua Zirkzee is a good enough player. But will he be a worthy replacement for Hojlund? I don't think so. Joshua Zirkzee played last season at Bologna. Adapting to the Premier League is a bit time-consuming. It is unlikely that he will fit into Manchester United's squad very quickly. But if Joshua Zirkzee can quickly adapt himself to Manchester United's players then he will surely become a worthy replacement for Hojlund.
At this stage, I believe we can only be concerned with adapting to the club, as some players struggle to get used to the Premier League in their first season. Joshua Zirkzee's stats for Bologna's previous season were not bad; he scored 12 goals in 37 appearances for Bologna. Despite the fact that the Premier League is difficult for some players, Hojlund managed to score 10 goals in the Premier League last season. If Zirkzee quickly gets used to the league and the club, I think he will be a perfect replacement for Hojlund.
There are still many weaknesses in Manchester United's squad. And I would say coach Ten Hag has yet to take the necessary steps to strengthen his squad. We don't see good performances from Manchester United players in friendly matches. I don't even see the possibility of this team doing well next season. Manchester United cannot be in the top four of the table.
Manchester United, in my opinion, can finish among the top four teams next season because the club currently has the players needed to beat any of its opponents, If Manchester United fails to finish among the top four next season, Ten Hags must accept the blame because the club provided him with what they needed. Furthermore, if Manchester United injured players are ready to play and Ten Hag improves the players, I think the team will perform well.
