I think Manchester United is most favorite team to win UEFA Europe League tittle in this season after success eliminating Barcelona on playoff round, unbelievable with Manchester United performance in this season although failure finished with top standing position on group stage and should face Barcelona at playoff round but success win dramatically.
Up coming on 16th round, Manchester United against Real Betis and the last success match with La Liga team I think has potential for Manchester United continue the winning trend with Spanish team.
There is actually a chance for Manchester United to win the Europa League but also consider so many teams that are still in the competition. The likes Juventus, Roma and Arsenal are still in the competition which means it is still an in predictable trophy yet because anybody can win it.
