Sheffield United loanee Chiedozie Ogbene will be hoping to keep his and the Republic of Ireland’s World Cup dream alive on Sunday afternoon.

Sheffield United winger Chiedozie Ogbene has described the Republic of Ireland’s final World Cup qualifier against Hungary at the Puskás Aréna on Sunday afternoon as an “all or nothing” battle.

The Republic of Ireland will head into their final qualifier for next summer’s World Cup knowing they must secure all three points to keep their hopes of securing a spot in the United States, Mexico and Canada alive.

Following Thursday night’s shock 2-0 win over Portugal in Dublin, Heimir Hallgrímsson’s side are third in Group F on seven points, one point behind second-placed Hungary and three back on table-toppers Portugal, who face Armenia in their final qualifier also on Sunday afternoon.

With the Republic of Ireland needing to finish second in the group to secure a play-off spot and keep their qualification dream alive, nothing other than a win will do. And for Ogbene, who played a key role in the win over Portugal, he knows exactly what is on the line for him and his teammates.

Ogbene: ‘We must win’

"This result hasn't defined us yet," the Blades loanee told BBC Sport NI. “We have to go to Hungary with a level head and we must win.

“It's all or nothing, really. We can't go there and try to get a draw as it won't do us any good, so we need to win this game.

"We know it's going to be difficult and they will know we have to win, so will be doing everything in their power to frustrate us. We just have to take this momentum and this feel-good factor and take it into Sunday."

The midweek victory over Portugal also saw Cristiano Ronaldo sent-off for throwing an elbow at Republic of Ireland defender Dara O’Shea, resulting in the home side earning a numerical advantage for just under the last half hour.

Ogebene felt throwing an elbow was Ronaldo’s way of expressing his frustration at getting no change out the Republic of Ireland’s defence, adding: "Frustration can kick in and happen to the best of us.

"Cristiano Ronaldo is one of the best players in the world, if not the best, and it happened to him, but that's credit to the boys and how they defended."
