Rory McIlroy has sent a message of good luck to the Northern Ireland football side ahead of their Euro 2016 opener against Poland tomorrow.

The world number three golfer produced a motivational video which Michael O'Neill's side watched. In it, McIlroy emphasises the importance of representing your home country and the exhilaration that comes with winning a major competition.  

He said:

"Coming home as a major champion was one of the proudest moments of my career so far. It's an honour to represent Northern Ireland around the world - and to put our wee country on the sporting map."

"Tomorrow you will write the next chapter in our long and famous sporting story. When you walk out at that stadium in Nice, take a moment to think about our sporting icons, what they achieved, and how this is your chance to take your place alongside them."
