Donald Trump has sent his congratulations to Conor McGregor after his UFC return.

McGregor returned to the octagon with a 40-second victory over Donald Cerrone in Las Vegas.

The Irishman has received plenty of plaudits for his display with the latest coming from the President of the United States.

McGregor has previously sent Trump a congratulations of his own after he celebrated three years since he was sworn into office earlier this week.

The UFC star branded Trump a "phenomenal president" before suggesting he was one of the greatest of all time.

"He sits atop the shoulders of many amazing giants that came before him. No easy feet. Early stages of term also. Incredible," the Irishman wrote on social media.

And Trump sent a response to McGregor, posting: "Congratulations on your big UFC win."

McGregor's next fight opponet is unclear after he called out four of his rivals before the win over Cerrone - including Khabib Nurmagomedov and his upcoming opponent Tony Ferguson.

McGregor is also plotting a run at the 170lb title held by Kamaru Usman, and the BMF belt held by Jorge Masvidal.

"I guarantee he fights Nate Diaz next," UFC legend Bisping told ESPN.

“Khabib isn’t going to fight him next, he is going to fight Tony Ferguson on April 18 and he will then have Ramadan.

"So even if beats Tony, he is not going to fight anyone else soon.
