Daniel Agger made 175 appearances for and captained Denmark at Euro 2012 but has gone on to pursue his dreams even more in retirement.

The 40-year-old is the current assistant head coach of his national side alongside Brian Riemer, but also is a qualified tattoo artist and has since invested in a sewage company.

Agger, who spent nearly a decade on Merseyside, was known for being a fierce defender with a very capable left foot.

He only played for two clubs his entire career, Liverpool and Brondby, before retiring in 2016 at just 31.

Since hanging up his boots, however, Agger became a qualified tattoo artist and invested in one of the world's biggest parlours - Tattoodo.

"I was about 15 and on a school trip to Paris," Agger said as he detailed the birth of his love of ink to their website.

"It wasn't something I'd thought about before. Me and a friend went into the shop and said that's what we're going to have and we got it. I still have it today."

Since getting his first tattoo at 15, Agger has many additions and the majority of his body is covered, including a Viking graveyard sprawled across his back.

"I see it as one piece," Agger explained. "When I speak to people I talk about my tattoo as one piece but obviously every tattoo has a story, some better than others."

He also got 'YNWA' on his knuckles, referring to those fond years at Liverpool, which he confirmed was stamped when he was being linked with a move away from the club.

"Timing was quite good," he added. "[There were] a lot of rumours sending me to another club for a lot of money but I knew I was staying.

"Somehow I wanted to show that to the footballing world and this was a way I wanted to show it."

In 2013, he also started a sewage management company in Denmark, named KloAgger (translated to Agger toilet in Danish) after putting up £450,000.

He largely takes a backseat in the firm, however, with his younger brother Marco and their friend Rune Ruasmussen overseeing the operation.

Agger has also made a return to football in the past few years alongside his charitable ventures in Denmark, becoming head coach of second-division side HB Koge.

He also registered as a player again, turning out for the Swans, before leaving them via mutual consent after two years.

A little over 12 months later he accepted a position as Denmark assistant with Riemer, most recently finishing second in a Nations League group with Spain, Serbia and Switzerland.
