Danish national football team captain Daniel Agger has announced his retirement due to injuries at the age of just 31.
"It's sad, but it is the right decision to stop. I'm proud of my career," the Danish international centre-back wrote on Twitter.
Agger began his professional career with Brøndy in 2004 and led the club to the Danish championship the following year. He joined Liverpool in 2006, where he made 232 appearances, scoring 14 goals and winning the League Cup in 2012. But his spell at Anfield was frequently disrupted by injuries and he returned to Brøndby in 2014.
"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," he said at a press conference at the Rosenhøj Boldklub outside Copenhagen where he played as a youth.
"I don't want my level to fall any further and so it was time to stop," he added.
