Robbie Keane is supremely confident that he can still contribute to the Republic of Ireland cause.

The LA Galaxy striker is closing in on his 36th birthday but believes he still possesses the ability required to score goals for his country at Euro2016.

Ireland open their Group E campaign against Sweden in Paris on Monday and the country's all-time games record holder and all-time goalscorer feels he can do a job for Martin O'Neill's side.

"Yes, of course, there's no question about it," said Keane who has 67 goals in 143 internationals.

"Just because I've been around for a long, long time - there are other players at this tournament who are the same age as me, but maybe started their careers internationally a little bit later than I did.

"There are certainly goals left in me, there's no question about that. I've been doing it since I was 17 years of age and I've continued to do it and I have been consistent in doing that, so there's no question about that.

"I'm fairly confident in my ability when given the opportunity.

"First and foremost, I'll do my best for the team, but if there's a chance there, hopefully I'll take it."
