If Tottenham and Manchester United were to play the finals, I think Tottenham will win it as Tottenham has been able to win some games that I thought they'll lose this season. Manchester United aren't focus enough although they have managed to qualify for the knockout stages of the Europa league and they have to know now that anytime that they play badly, they'll be removed from the competition as the knockout stages aren't where you come to play.
Only one of them appears in the Europa League final match is already difficult, and both of them joining the final match is very likely impossible. I don't think it will happen and I am not sure they belong to two different branches so that they won't meet each other sooner than the final match.
There is certainly no way Tottenham and Manchester United are winning the Europa League title this season, both team don’t look prepared and determined enough to me especially Tottenham who have been losing games back to back recently and United on the other hand are not consistent, they win a game today and are likely to lose the next game so it’s a major doubt for me except something changes.
Two clubs with big problems and at 13th and 14th ranks in
Premier League are not competitive enough to win Europa League. They have problems so that they currently have very low ranks in their domestic league, and it's unlogical to consider they are stronger than many competitors in Europa League from top 5 leagues or beyond top 5 leagues. There are competitors in Europa League that have better forms than both Manchester United and Tottenham Hotspur and in cup, your tradition can not your club winning a cup, your form and performances decide.
