Chelsea has a good chance to win this season they win this league with hard work and good performance and Manchester United and Chelsea's records are not equal because manchester united is weak if they win this europa league it will be a good win for manchester united Chelsea is the better because Chelsea tend to improve after losing a match and Manchester United have been keeping their list of poor performances for a long time. Manchester United had some chances in which they could have improved themselves but they kept their poor performance bad. Chelsea's performance is better than Manchester United's because they are playing with good performance and hard work.
Although the comparison you said is very clear, but Chelsea must fight to be able to maintain themselves in the top four if they want to be in the Champions League next season, because the Conference League that Chelsea might be able to win will not be able to bring them to the Champions League next season. So Chelsea must fight for the top four in the Premier League standings, while Manchester United must fight in the Europa League so that they can be one of the candidates for the Champions League next season if they are able to win the Europa League this season. And from that comparison it is quite clear who is the best, but if Manchester United can win the Europa League this season, the team will not be in vain occupying the lower rankings in the Premier League.
