Although Manchester United and Tottenham are the two top Premier League teams which playing in the Europa League this season, but I personally am not at all sure for them to win the trophy. Because I still make a benchmark for last season about Liverpool because anyway, when Liverpool became a very favorite team also that Liverpool was still in the title race in the Premier League standings but Liverpool still failed in the Europa League in last season.
I don't think either of Manchester United or Tottenham are among the favourites to win the Europa League. They struggle with average teams how are they going to do when they face tough opponents? Manchester faced Liverpool at home and got slapped 3 goals without reply, how would it have been if they had been away at Anfield that day?
Tottenham have not been able to win Leicester City and Newcastle this season, I don't see them as a team that can go all the way in The Europa.
When people mention the top teams in the Europa, they include Manchester United because they're a big team, but based on current form, there are at least 5 clubs way better than Manchester United.
The good thing about the Europa League is that the winner is mostly unpredictable. It's not like the Champions League where you can mention one of the top 5 teams and have a 95% chance of getting the winner.
Manchester United or Tottenham have qualified for the European League, but their chances of winning the European League title are not very high. Manchester United were early favourites, just like we had Liverpool last season, but last season Liverpool performed much worse than expected and crashed out of the Europa League. Manchester United have failed to perform well in most of the matches they have played in the recent season. If they perform the same in the Europa League tournament as they have done in a few league matches, they won't be able to go far with this performance. Still, since there is still time to plan, they should plan and try to move forward by performing well. The two teams that performed well last season are not in this season's Europa League, so if they can perform a little better, they will have a chance.
