Republic of Ireland 0-0 Portugal: Selecao held to set up tantalising Serbia decider in Group A
Portugal travelled to the Republic of Ireland for the first time since 2005 but could only muster a draw against Stephen Kenny's side.
Portugal were held to a goalless draw by the Republic of Ireland to leave Sunday's clash with Serbia as the decider for top spot in World Cup qualifying Group A.
Fernando Santos' men had scored 16 goals during their five-game winning streak across all competitions but could only muster two shots on target during a frustrating outing in Dublin.
Cristiano Ronaldo went the closest, though even the all-time leading scorer in men's international football could not break the deadlock in Thursday's clash.
The visitors, who saw Pepe dismissed late on for two bookable offences, and Serbia both sit on 17 points with one game remaining as the latter travel to Lisbon for a winner-takes-all decider.
