A number of key players were in the starting line-up
Manchester United got off to a losing start in the Europa League.
Jose Mourinho's side lost 1-0 at Dutch top flight side Feyenoord.
United had a number of first team players in the spine of their team, from David De Gea in goal and Eric Bailly in defence to Paul Pogba in midfield and Marcus Rashford up front.
But they couldn't get the win in Rotterdam as Tonny Vilhena converted a Nicolai Jorgensen cross.
