Martin O'Neill: It's hard to believe we're unbeaten in the group, but we need another grandstand finish

A defiant Martin O'Neill has warned people not to write off the Republic of Ireland's World Cup qualification hopes as they target a crucial victory over Serbia.

The Republic returned from Georgia during the early hours of Sunday morning facing strong criticism of their display in a 1-1 draw in Tbilisi, with O'Neill himself admitting their first-half performance was as poor a 45 minutes as they have produced during the campaign to date.
