The former Wimbledon champion made the comments while providing analysis during Andy Murray’s first round encounter at the French Open against Andrey Kuznetsov.
During play, it was mentioned how Murray is a big Hibs fan with his grandfather having once played for the club.
McEnroe, though, remained silent, not recognising Hibs or their official name Hibernian.
He then said: “I needed a little helping. Glasgow Rangers is as far as I’ve got.”
