Craig Bellamy says Manchester United are nowhere near Manchester City and Liverpool.
Bellamy, now reserves coach at Anderlecht, is a former City and Reds striker.
He told Sky Sports: "Coronavirus hit, and it seemed to be quite a good time at Manchester United, everyone is talking about Manchester United, but they are nowhere near these two clubs.
"Nowhere near. And it's going to take a good three or four years to get near.
"The balance [City and Liverpool] have in the team, the way they play, the intensity they play at, the pressing and understanding of what they're doing, takes them well ahead. These two teams are a big gap ahead of anyone else."
