He said: “I have had the opportunity to work with the players since last November, and we are well prepared as we embark upon the first of our qualifiers next month.

“Oman will provide a good test to start our trip before we travel to Tbilisi. We are focused on the task in hand, and look forward to the challenges ahead of us.”

There are no uncapped players in O’Neill’s latest squad, but he will also be without veteran defender Richard Dunne, who announced his retirement from international football during the summer.

The party includes former first-choice goalkeeper Keiren Westwood, who has returned to club action after joining Sheffield Wednesday following his release by Sunderland at the end of the last campaign.

O’Neill has confirmed that Los Angeles Galaxy striker Robbie Keane will remain his captain.

Ireland, who failed to qualify for last summer’s World Cup finals when they finished fourth in their group behind Germany, Sweden and Austria, have been handed a tough challenge once again this time around.

They have been drawn into Group D with the Germans, the new world champions, Scotland, Poland, Georgia and Gibraltar.

They made it to the finals of the last European Championships in Poland and Ukraine in 2012, but lost all three group games as they embarked upon a downward spiral which ultimately cost then manager Giovanni Trapattoni his job.

O’Neill, assisted by Roy Keane, took over in November last year and his seven friendly matches to date have brought one win, three draws and three defeats, although the manager deliberately chose challenging opposition – Turkey, Italy, Costa Rica and Portugal – for the end-of-season programme.
