Top 10, really?
Since when top 10, bottom of top 10 is a success for Manchester United?
With a position in top ten, like 10th, 9th, 8th position, they won't get any slot to UEFA leagues next season, that's failure, not success, and it's unacceptable. They have to finish this season in top six to at least appear in UEFA Conference League that I think is not interesting with them. They will try to play and win UEFA Europa League and this will help them eligible for UEFA Champions League next season. Because in Premier League, they have no way to end with high position that is eligible for Europa League.
I agree with you. A top 10 finish will surely not be a success for Manchester United and it is unrealistic to say they can finish within that range or talk more about qualifying for a European competition next season. Their best chance of playing a European competition next season is by winning the Europa League which would grant them automatic qualification to the champions League. Given their current form they must prioritize consistency and improve their performances to achieve this goal.
