Conor McGregor has put the UFC lightweight division on high alert with an ominous message.
Set for a return to the Octagon against Dustin Poirier in the coming months, the Notorious one is training hard after taking the summer off in the south of France.
And after Khabib Nurmagomedov's triumphant retirement last month opening up the division, many lightweight fighters would fancy their chances of grabbing hold of UFC gold.
But as one of the greatest rides off into the sunset, perhaps the biggest name in the sport is back and out for redemption.
After his Khabib loss in October 2018, McGregor sought to make a comeback and fight a 'season' in 2020.
But the Dubliner only got in the cage once this year in a 40-second dismantling of Donald Cerrone in January as clashes with UFC chief Dana White and the Covid-19 pandemic got in the way.
With McGregor now more than willing to make a return and restart his return, he's lined-up to face Poirier in a rematch of their 2014 bout.
Sharing a highlight reel of his best moments on Instagram, he warned his rivals ahead of the fight: "You can run, but you can't hide".
The Dubliner last week shared a glimpse of preparations for his next fight and added to his 'Notorious' and 'Mystic Mac' nickames by labelling himself 'The Pay Per View Monster'.
McGregor, 32, promised a fan on Twitter that he is 'raring to go' for a clash against Poirier, who he beat in Las Vegas six years ago. However, the fight has yet to be officially confirmed by the UFC.

“I am raring to go and in the best place I’ve ever been,” he told the fan.
“Excited to show my practices to the world! Still awaiting official confirmation however.”
His latest social media post came after McGregor has sent a message to America with the world awaiting the announcement of the US election result.
