Paul Scholes secured his first job in management on Monday and some fans believe one man will be relishing the chance to see him fail.
The 44-year-old former Manchester United
midfielder has been confirmed as the new boss of League Two Oldham, signing an 18-month deal with the club.
And the pressure is on with the now ex-BT pundit having been highly critical of other managers in the past, most notably Mourinho.
Mourinho was sacked by United in December after just seven wins in the club's first 17 Premier League games of the season.
Scholes took aim at Mourinho several times during the campaign, branding the Portuguese a 'moaner' and an 'embarrassment' as well as claiming he orchestrated his Old Trafford exit.
And supporters believe Mourinho, who has been doing punditry work over the past couple of months, will be eager to return the favour should Scholes struggle.
'I pray Scholes doesn't flop,' wrote one on Twitter. 'If he does Mourinho is coming for him.'
'Scholes is a manager, Mourinho is a pundit,' tweeted another. 'This is going to be a lot of fun.'
