Ole Gunnar Solskjaer feels Manchester United must conduct "clever business" in the summer following their humbling exit in the Champions League.
Solskjaer admitted in the immediate aftermath of their 3-0 defeat in Barcelona, which sealed a 4-0 quarter-final win on aggregate for the Catalan giants, that he faces a major rebuilding job to re-establish United among the European elite.
In a previous era United were able to attract the world's best talents but, despite their track record of spending big in recent years, that may no longer be the case.
They have a battle on their hands to finish in the Premier League's top four but Solskjaer is already envisioning a scenario in the future where United are on an equal footing with their conquerors on Tuesday night.
"Yeah, that is the level we have to aspire to because that's the level we have been," Solskjaer told MUTV.
"We want to get there and we have to get there by hard work and attitude every single day, and of course some clever business we have to do and just keep on going."
