The Red Devils have found themselves under intense pressure in recent weeks after they slumped to back to back defeats in the Premier League under Jose Mourinho.
Their surprise 3-0 loss to Tottenham at Old Trafford on Monday night left them with just three points to show from their opening three Premier League games.
Mourinho is under pressure to deliver the title at Old Trafford, with Manchester United not having won the Premier League since back in 2013.
However, Manchester United’s current form places them well off the pace in the race for the top flight title this term.
Manchester United will look to get back to winning ways in the Premier League on Sunday afternoon when they travel to Burnley in the top flight.
And Robson feels that the Red Devils will have to keep their team spirit up as they look to try and bounce back and get their season back on track after a difficult start.
Speaking to Manchester United’s website, Robson said: “We have got to stick together because nobody outside of this club is going to stick with Manchester United.
“If the fans are not encouraging the team, the more the media are going to jump on the bandwagon and hammer the team even more.
“This is a time when you dig in together in the trenches, pull for each other and get that confidence back. The lads have got to put more hard work in, but with the squad of players we have got we can turn this around.”
Mourinho is under pressure to deliver a trophy after the Red Devils finished second and without silverware last term.
