Conor McGregor has beaten Donald Cerrone in 40 seconds on his return to the UFC.
McGregor had not won inside the UFC's octagon since capturing his second UFC world title in November 2016, and was submitted in four rounds by undefeated UFC lightweight champion Khabib Nurmagomedov at UFC 229 in October 2018.
McGregor had said earlier in the week that he would look to "acquire rounds" against the American, but he showed no such patience as he came storming out of his corner and threw a huge left hand right from the very start that signalled his intent to claim a fast finish.
He then connected with a series of shoulders to the face from the clinch before following his man across the cage and connecting with a huge head kick that badly rocked Cerrone.
A series of heavy left hands followed as Cerrone crumbled to the canvas, where he received a further barrage of strikes that sealed victory.
