Manchester United manager Ole Gunnar Solskjaer is dreaming of another memorable comeback in the Champions League but has admitted his side cannot afford to squander opportunities.

Barcelona did not deliver a vintage performance that has been their hallmark for over a decade but came away from Old Trafford with a 1-0 win after the first leg of their quarter-final following Luke Shaw's 12th-minute own goal.

United showed plenty of endeavour in attempting to equalise but failed to hit the target, with Diogo Dalot and Marcus Rashford both guilty of spurning decent opportunities when well placed.
