Daniel Agger has admitted that he was not fully fit when playing for Liverpool FC against Chelsea last Sunday.

Agger, who is suffering with a groin problem, had to stand in for Martin Skrtel who was too ill to play at the weekend.

However, Agger has now ruled himself out of Denmark’s international friendly this week, as he feels the need to rest after going through 90 minutes with a knock, but hopes to be back to full fitness for Liverpool’s Premier League clash with Wigan on Saturday.

“I should not have played on Sunday but Skrtel was ill and there was not much I could do,” he said.

“I was thrown into it. I have a pulled groin. It was something that should have kept me out on Sunday but it did not. I played the game. It takes hopefully only a few days (to recover).

“The reason why I have cancelled for Wednesday is that it is a bit early to play three days after I played 90 minutes with a groin problem.”

Agger has also expressed how pleased he is to have won his second Denmark’s Player of the Year award.

“Winning this award is one of the greatest things you can achieve as a Danish footballer,” he added.

“I have been down and out with injuries but awards like this make me want to keep going. It is my attitude that means I am standing in this position.”
