Ruben Amorim has warned Manchester United fans that the rest of the season is going to be a "rollercoaster." United followed up positive performances against Liverpool and Arsenal with a lacklustre display against the Premier League's bottom side Southampton on Thursday.

Could Ruben Amorim's pursuit of Premier League defender solve Manchester United's left-back crisis? Fans will be eager to see if the club makes its move before the transfer window slams shut.

Amorim did, however, admit he made a mistake in terms of his selection when putting the tired Ugarte up against Southampton’s energetic midfield. “Also, it is my fault because if you lose the timing of the pressure, if I don’t explain it well, the pressure is always lost in that, and you feel it today,” he added.

Manchester United boss Ruben Amorim has welcomed the pressure to perform and feels it could be the factor which would help them turnaround their form in the Premier League. United are currently 14th in the points table.

Amorim would like United to build up with a genuine three at the back, rather than the four it has been when protection is the first priority. At Anfield, United took the lead because Martinez sensed a moment to press high, snapping into Mohamed Salah to win the ball and then stay up to receive Fernandes’ slipped pass.
