Manchester United legend Gary Neville believes his old club have been clever in the summer market.
It turned into a more subdued transfer window than expected, with just three new additions in the form of Harry Maguire, Aaron Wan-Bissaka and Daniel James.
But Neville told ESPN: "I think there are three or four players at Old Trafford who have higher levels of quality that in a perfect world, Ole [Gunnar Solskjaer] would probably like them all out at once.
"But actually, if they left it would weaken the team that badly it'd mean that they wouldn't challenge for the Champions League. I think what Ole has to do is to get rid of one at a time. I think it's a clever transition out of what has been a poor transfer strategy for the last four or five years.
"You can't get out of it in one year, it's going to take two or three years of good culture and tone, in terms of what they're doing, to get out of what they've done. "You can't lose [Romelu] Lukaku, [Paul] Pogba, [Anthony] Martial all in one - you'd be absolutely decimated.
"The dressing room would be shot to pieces. You could maybe lose them over a period of two or three years if they wanted to leave."
