If Utd win europa league, would that end up having a better season than Spurs. 2 trophies and CL football next year against 2nd in league and the same CL football.
For the next year or two I'd imagine most rivals would try to suggest Spurs did better. But in time it'll go back to the history books. One team has 2 trophies and one had zero.
I know now what I'd deem more successful.
