Former Liverpool defender Daniel Agger has shocked the football world by announcing his retirement from the game on Thursday.

The Denmark international will hang his boots from both international and club football. Agger's retirement at the age of 31 comes as a shock and this comes just two years after he left Anfield.

Agger admitted that it was a tough decision, but admitted that he had to stop in order to allow him to stop himself from playing football to avoid a drop in form.

"It's been a tough decision but I am pulling the plug," Agger said during the press conference, as quoted by Sky Sports.

"It has been difficult in recent years. The last two-three years I think I've been at an acceptable level. But acceptable is not good enough for me. I don't want my level to fall any further and so it was time to stop."

In addition to this, the central defender took on Twitter to thank his fans for their support.

"Thank you for your support. A great experience.It's sad,but it is the right decision to stop. I'm proud of my career," Agger tweeted.

He joined the Merseyside club from Brondy in 2006 and after spending eight seasons with Liverpool, he returned to his former club. Altogether Agger has spent four seasons at Brondby, two seasons before joining the Red and two after.
