Arsenal striker Olivier Giroud could be regretting calling out UFC star Conor McGregor after the explosive star knocked out Eddie Alvarez at New York’s Madison Square Garden on Saturday night.

With his second-round knockout, McGregor becomes the only UFC star to hold two belts simultaneously.

It was a completely dominating performance from McGregor, who had Alvarez down three times in the first round before eventually stopping him with two minutes left of the second round.

McGregor, the reigning featherweight holder added the lightweight belt to cement his place as the UFC’s biggest draw.

His next opponent has yet to be announced and Arsenal striker Olivier Giroud might be well advised to keep his head down after jokingly calling out the UFC star in an official Arsenal video a few weeks ago.

In a series of quick-fire questions with Arsenal teammate Laurent Koscielny, Giroud said his worst subject at school was philosophy before being asked how long he’d last in a fight with McGregor.

Giroud said “10 seconds” which led Koscielny to ask “really?” before Giroud stated he’d never been in a cage before.

However, that didn’t stop Giroud calling McGregor out saying, “It would be nice to try. So, McGregor… when you want”, before winking at the camera.

The France international hasn’t had the best start to the season. He has lost his place in the side to the in-form Alexis Sanchez and has voiced his discontent.

According to the Daily Star, Giroud is set to meet with manager Arsene Wenger to discuss his role within the team.

However, he might get a chance to start in their next Premier League game against Manchester United with Sanchez currently struggling with a hamstring injury.

In other Arsenal news, the club is set to step up its bid to sign Swedish wonderkid Peter Gwargis.
