Robbie Keane has been included in Martin O'Neill's Republic of Ireland squad for the final time having announced his impending international retirement.

The LA Galaxy striker confirmed on Wednesday that he will step down from international football following next week's friendly against Oman.

Keane, who has formerly represented the likes of Tottenham, Liverpool and Inter, has scored a record 67 goals in 145 games for Ireland after making his debut against the Czech Republic in March 1998.

"Robbie's appearances and goals for Ireland speak for themselves," Ireland manager Martin O'Neill said.

"He is undoubtedly one of Ireland's finest ever players and I do not see his international goal record being beaten for a very long time, if ever. It will take us some time to get over his absence."

John O'Shea, Seamus Coleman and Jeff Hendrick are all included for the friendly against Oman and Ireland's opening World Cup qualifier versus Serbia in Belgrade despite being fitness doubts.

The trio are set to be assessed by the FAI medical staff, but Shane Duffy - who will miss the Serbia game through suspension - is not in the squad.
