Republic of Ireland manager Giovanni Trapattoni faces a real selection headache before the all-important 2014 World Cup qualifier against Germany.

Already without striker Kevin Doyle because of a thigh problem, the Italian coach could be deprived of few more first team regulars.

Centre-back Sean St Ledger picked up a hamstring problem in the Leicester City’s win over Bristol City, whereas Sunderland winger James McClean has injured his tie in the 3-0 defeat to Manchester City.

On top of that, Stoke midfielder Glenn Whelan was substituted just 20 minutes into the goalless draw with Liverpool because of a hamstring injury, with all three players now doubtful for the Germany clash.

Manchester United’s Robbie Brady and Sunderland’s David Meyler has already been handed additional call-ups, as Giovanni Trapattoni waits for the medical team to assess the aforementioned players.

Republic of Ireland take on Germany at Aviva Stadium in Dublin and the Irish are 7.50 (13/2) with bet365 to beat the Group C leaders.

Ireland squad:

Goalkeepers: Keiren Westwood (Sunderland), David Forde (Milwall), Darren Randolph (Motherwell);

Defenders: Stephen Ward (Wolves), Stephen Kelly (Fulham), Marc Wilson (Stoke), John O’Shea (Sunderland), Sean St. Ledger (Leicester), Paul McShane (Hull City), Darren O’Dea (Toronto FC);
