Conor McGregor has slammed 'slap head' Thierry Henry on the 10 year anniversary of his infamous handball that cost Ireland qualification for the 2010 World Cup.
The UFC star, who is currently in training for his return to the Octagon early next year, was wishing the Ireland team luck before last night's 1-1 draw with Denmark.
His tweet, which was liked almost 16,000 times, said: "Come on you boys in Green!!! Sending big energy towards our Ireland national team tonight as we fight for qualification for Euro 2020!
"Redemption for aul slap head Thierry Henry’s handball all them years ago, begins TONIGHT! Let’s go Ireland."
Henry infamously handled the ball twice in the lead up to a French goal in Paris that made the score 1-1 in the second leg of a World Cup qualifier after Ireland had lost the first leg 1-0 back in 2009.
Meanwhile, McGregor is set to make his long-awaited return to the Octagon on January 18, having not fought since being choked out by Nurmagomedov in October last year.
It has not yet been revealed who McGregor's next opponent will be, although fellow lightweight Donald Cerrone is the likely contender.
After that fight, former two-weight UFC champion McGregor wants to fight Jorge Masvidal after his win against Nate Diaz at UFC 244, before rounding off 2020 with a rematch against Nurmagomedov.
But Nurmagomedov has told McGregor he needs to win not two, but 10 straight bouts to earn the chance to face the Russian again.
“As for a rematch, to fight for a belt in the UFC, I remember I had something like nine or 10 fights," Nurmagomedov said in quotes reported by MMA Junkie .
"If he wins 10 fights in a row, then that’s completely possible."
