Denmark defender Daniel Agger has announced his retirement from football – and Liverpool fans took to Twitter to express their respect for his career.

The former Liverpool star, who is hugely popular among supporters following eight years at Anfield, confirmed he is hanging up his boots at the age of 31.

“It has been a tough (decision), but I am pulling the plug.” said Agger on Thursday, as quoted by Fox Sports.

The centre-back spent eight years at Anfield, where he made 232 appearances in all competitions. His career at the top level lasted 12 years in total.

Agger returned to his boyhood club Brondby in 2014, after his relationship with Brendan Rodgers appeared to have broken down.

The two-year contract he signed has now expired and the centre-back has decided to call time on his career.

Here are some of the messages on Twitter:
