The BBC presenter has joked about the Scot during his days as Manchester United manager.
Indeed, Lineker referenced Ferguson's claim that he never held a grudge... and followed it simply with typed out laughter.
The former Manchester United boss famously fell out with a number of his players and refused to do interviews with the BBC for a number of years.
Hence Lineker's comment on social media:
Sir Alex says he never held a grudge. Hahahaha.— Gary Lineker (@GaryLineker) October 14, 2015
Manchester United face a tough trip to Everton at 3pm this Saturday afternoon and it'll be a test of just how far Louis van Gaal's side have come.
United drew plenty of plaudits after reaching the summit of the Premier League prior to their clash at Arsenal. But a 3-0 loss to the Gunners at the Emirates Stadium exposed some serious flaws within the United side - and made Van Gaal look very bad indeed tactics and selection wise.
That's why Man United can send out a strong message by bouncing back against a tough Everton side. But more of the same away-day woes won't exactly will their fans with confidence.
