Denmark midfielder Christian Eriksen has admitted that he was "nervous" all day and all night ahead of his side's win over the Republic of Ireland on Tuesday.

Tottenham Hotspur man Eriksen shook off his nerves to score a hat-trick and send his side to the World Cup in their playoff match after last Saturday's first leg ended in a goalless draw.

"I know how nervous I was all day and all night, looking forward to the game," Eriksen told Sky Sports News.

"I was trying to keep my nerves down, get involved, get the ball as much as possible compared to the first game, but of course we got the ball, played a lot better than the first game, created chances and luckily got five goals.

"It's an incredible feeling [to score his hat-trick] and we've been fighting for so long to get there, we've had two very hard playoff games, but with the result we got tonight we can be very pleased. I am looking forward to the World Cup."

Eriksen will now return to Spurs for this weekend's North London derby against Arsenal.
