United were well off the pace at the King Power Stadium against their fellow top four hopefuls.
And as their Wembley dreams were dashed, Solskjaer defended his sides performance, insisting they have been exemplary in a number of important games recently, but there are some squad members who haven’t played enough recently.
“We didn’t have the spark tonight – but it’s understandable,” Solskjaer told BBC Sport. “This team have been fantastic in the last three or four months.
“We played every three days and been on a great run. It just caught up with us, all the games and travels.
“Thursday night in Milan was a big night and took a lot of out of us physically. We didn’t have the extra zip, authority and confidence today.
“We tried to get on the front foot and start well because sometimes you can get that adrenaline boost and confidence if you get a goal and that can carry you over the line.
“We’ve got too many players that have played too many games and too many that haven’t really had much football, Anthony Martial, Donny van de Beek, Paul Pogba and others are trying to get in who haven’t had enough football. We didn’t have enough against a tough team.”

“We’ve got the Europa League and Premier League to concentrate on,” the Norwegian added.
“Yes we would’ve liked to go to Wembley but now all the focus is on the games we do have.
“We’re in a good position in the league and we want to keep improving, of course Leicester are just behind us so it won’t be easy but we want to keep going and get as far as possible in the Europa as well.”
