United registered one of their worst displays since Solskjaer took over from Jose Mourinho and after a poor first half, they fell behind following goals from Raul Jimenez and Diogo Jota.
Rashford struck a late consolation in injury time, but it wasn’t enough to rescue United, who crashed out of the competition at the quarter-final stage.
And the Norwegian admits United did not have “enough quality” in their attacking third and was unhappy with the link-up play between his three forward players.
“We started too slowly and played into their hands.
“Our possession wasn’t bright enough and quick enough, so it’s disappointing.
“I didn’t think we had enough quality in the last third, enough combination play.
“We had decent dominance with the ball in the first half but that doesn’t help if you give the ball away and they can counter.
“This was a big step backwards, mainly because of the quality of the possession and the passing,” Solskjaer told BBC Sport. SHARE THIS STORY USING ANY OF THE BUTTON BELOW ⬇ PLACE YOUR TEXT ADVERT BELOW ⬇⬇⬇
