Nice owner Sir Jim Ratcliffe says the Glazers have "lost the plot" at Manchester United.
Ratcliffe hit out at the club's irresponsible transfer investments since Sir Alex Ferguson's retirement in 2013, and compared United's contrasting approach to the current set-up at Nice.
He told The Times: "United have spent an immense amount since Ferguson left and been poor, to put it mildly. Shockingly poor, to be honest.
"We have a different approach here (at Nice) to be moderately intelligent about it. Try to do it more grass roots, trying to locate young talent.
"Some clubs seem to have an ability to do that, Southampton, Lille. United have done it really poorly. They have lost the plot there somehow."
