Martin O'Neill: Ireland need ‘phenomenal effort’ to beat Serbia

"We'll have to be really, really at our best to win the game - but we can do that."

Martin O'Neill admitted the Republic of Ireland have to beat group leaders Serbia to get their World Cup qualifying campaign back on track after surviving a major scare in Georgia.

The Republic, who started the day level on points with the Serbs at the top of Group D, ended it two adrift after having to make do with a 1-1 draw in Tbilisi despite taking a fourth-minute lead.
