Ruben Amorim has warned Manchester United’s campaign will continue to be a “rollercoaster” as players try to adjust to his system mid-season.

It took a stunning 12-minute hat-trick from Amad Diallo for United to come from behind late on and beat Premier League basement boys Southampton 3-1 on Thursday night, after a first half in which the optimism from good recent results away to Liverpool and Southampton threatened to disappear.
