Glenn Whelan treats the shooting of the Republic of Ireland against Denmark when it's his last big game.

The 35-year-old Hearts midfielder believed that his international career had come to an end in the second half of Martin O & # 39; Neill's tenure as coach but returned under Mick McCarthy to rejoin the team.

However, with his 36th birthday nearing January, he knows that he has to enjoy every last minute he has left in the Green Shirt of Ireland, and the qualifying competition on Monday night could be as big as possible.

Whelan said, "This is what we want, that's why we're here, so we rock for friendly games if you have four or five days off on the beach, so you play for your country to take part in these games.

"There are children who dream of playing for Ireland. It could be the last big night for me and I will appreciate and enjoy it as much as I can, even if it's a big game.

"So that I can get a second bite on the cherry as it is – it was taken from me, I would never play for my country again and now, God, I am chosen tomorrow, possibly playing the biggest games in one of them in which Ireland has played.

"For me, I'll appreciate it, take it on board and although it's nerve-wracking and getting tight, I'll enjoy it as much as I can."

For center-back Shane Duffy, who will take over the Republic in the absence of suspended Seamus Coleman, it will also be a big night.

Duffy said, "It's a great honor, it's a major milestone in your career to play for your country and lead the boys out, I hope I can turn it upside down and not let it affect me ,

"I'm looking forward to it, my family will be proud and I'll be proud, but the main goal is to go out and just play the game and try to win."

This is something that Ireland has failed to do in its last five encounters with the Danes over a two-year period, despite four draws from a 5-1 draw in Dublin, Duffy and his teammates costing a trip to the 2018 world The cup final was overshadowed.

The defender of Brighton said, "Of course you will not forget such a night, it's a low point in our career for most of us who have played at night, but football is progressing fast and we have another chance.

"It's a different team, a different manager, and we're all excited and confident that we can achieve the result."
