Two men at the very top of their respective sports came to blows in the Octagon on Sunday as Cristiano Ronaldo paid Conor McGregor a visit in Las Vegas.

Ronaldo, enjoying his break after a memorable Euro 2016 campaign, is on holiday in America and took some time out to meet the Irishman as he prepares for a long-awaited return to UFC.

Always happy to whip off his t-shirt for a photo, a heavily-tanned Ronaldo posed in the octagon for a dramatic fight snap with McGregor... just imagine the pay-per-view figures on that one.

McGregor is just one month away from UFC 202 and a chance to avenge his defeat against Nate Diaz in Sin City.

The pair previously met at UFC 196 and were scheduled to fight again at UFC 200 before McGregor was pulled from the line-up due to a dispute surrounding his media schedule.

Now, though, the fight is set to take place on August 20 and Ronaldo took a look around the Dublin-born fighter's gym at the weekend. 

The Portuguese forward is taking a well-earned break ahead of next season, following European Championship success with his country.

Ronaldo was taken off on a stretcher in Portgual's final against France on July 10, but later returned to watch from the sidelines as his country recorded a famous win.

McGregor was not the only celebrity face Ronaldo bumped saw at the weekend, as the former Manchester United man was also spotted partying with Jennifer Lopez after watching her concert.

A video emerged of him in the front row of the gig at Planet Hollywood alongside a male pal, enjoying the sights and sounds of one of pop's biggest names.
