Republic of Ireland assistant manager Roy Keane has said that he is enjoying working with Martin O'Neill.

Ireland have remained unbeaten since O'Neill's appointment as manager four months ago, and Keane hopes that their good form can continue ahead of their Euro 2016 qualifiers later this year.

"I am enjoying working with Martin and (goalkeeping coach) Seamus McDonagh and all the rest of the staff and the players," FIFA.com quotes him as saying.

"But we know, obviously, the bigger tests are to come. If we couldn't have enjoyed the last few months, there's something wrong. We understand it will get serious in the next few months, and even with these friendlies - people have been very polite and give us good backing, but we are here to get results.

"We are under no illusions about that, Martin and myself. We have been in the game long enough. It's well and good getting pats on the back, but we are here to win football matches, and that will be tough. But we are ready for it."

Keane won 67 caps for the Republic of Ireland national side, scoring nine goals in the process.
