Manchester United will be "one of the top favourites" for the Europa League, says Tottenham manager Jose Mourinho.
United dropped into the competition after Tuesday's 3-2 Champions League loss at German side RB Leipzig meant they finished third in Group H.
United won the Europa League in 2017 under Mourinho, who has guided Spurs to this season's last 32.
"The teams that drop down are always strong teams, teams that normally don't belong to that level," he said.
"Manchester United are one of the top teams. The group was very hard - Paris St-Germain, Manchester and Leipzig, very hard.
