Northern Ireland striker Kyle Lafferty has declared himself fit for his side's Euro 2016 opener against Poland on Sunday.

The 28-year-old was faced with a race to be ready in time for the match in Nice having limped out of training with a groin problem on Tuesday.

However, he is now back training with the rest of the squad and insists that he has "never felt better".

"It's feeling good, I trained by myself yesterday, did a few runs, a few twists and turns and it feels good," he said in an interview with the Irish Football Association.

"Seeing the way I fell, the way I landed, I thought the worst, but I came through it and got the scan results which were all clear and I've never felt better. When I had the sharpest pain in my groin, I thought the worst, as you do, but the longer the day went on, I started feeling better as I was getting more stiff and that was probably a good sign.

"I went for a scan and the results came back clear and it gave me the go-ahead to start training intense again. I have and I feel great."

Northern Ireland will also face Germany and Ukraine in Group C.
