Roy Keane believes one of Manchester United's summer signings has been the biggest disappointment of the season so far.
United spent big in the summer as they looked to build on finishing third last term, but it has not paid dividends yet as they find themselves down in sixth after losing six of their opening 15 league games.
They are also on the brink of Champions League elimination, heaping the pressure on manager Erik ten Hag.
Much of United's issues in Europe have been put down to their struggles at the back, with goalkeeper Andre Onana making a number of high-profile errors.
