Lee Dixon has publicly questioned the existence of global warming in bizarre comments caught on TV.
The former Arsenal and England right-back was working as a pundit for the Gunners' 3-1 defeat against Manchester United at Old Trafford on Sunday.
And Dixon, 58, in a debate with commentator Peter Drury about why Premier League goalkeepers no longer wear caps, sarcastically asked 'has The Sun changed since the 70s?', before saying 'now we've got global warming... allegedly.'
He said: 'This is a question I think I asked last year that you might know the answer to, you might not. It's all about why don't goalkeepers wear caps any more? Has The Sun changed since the (19)70s?'
Drury replied: 'I don't know the answer... First of all, I'd say to you occasionally you still see one, but not as many as you used to, I agree.'
Dixon continued: 'All goalies used to wear caps when it was sunny. And now we've got global warming, allegedly, and all that.'
'Maybe we've got taller stands since the 70s,' Drury responded, with Dixon concluding: 'There you go. See, I knew you'd get a proper answer'.
Gunners icon Dixon made 616 appearances in all competitions for the north London side across his 14-year spell, scoring 28 goals and winning four league titles, three FA Cups, two (outright) Charity Shield Trophies and a European Cup Winners' Cup.
Mikel Arteta's side were defeated at Old Trafford after goals from Antony and a double from Marcus Rashford after Bukayo Saka had equalised.
