Dries Mertens' wife, Katrin Kerkhofs, has revealed she and the Napoli forward have previously had sex in the toilets of a moving train.
The couple have been together since childhood and got married in 2015 after becoming one of Belgium's most popular items.

Kerkhofs appeared on Belgian television channel Vier and delved into her life with Mertens and revealed a steamy detail.
She explained on Gert Late Night per Daily Star: "In public I behave like a lady, but in bed I am eccentric.
"I think that when you are sure of yourself on a sexual level, things are going better on a general level.

"I like to do it in places a little unusual, like the basin of a train. I like it a lot."
The 33-year-old is a television presenter by trade and even provided coverage of the 2014 World Cup in Brazil, while her husband played at the tournament.
Earlier this year, the pair welcomed their first child together.
Kerkhofs gave birth to a baby boy called Ciro Romeo in March.

Mertens rose to prominence with PSV Eindhoven before moving to Napoli in 2013 in a deal worth €13 million.
He's gone on to make over 300 appearances for Gli Azzurri and become their all-time top goalscorer with 148 strikes.
During his time in Naples he's won the Coppa Italia twice, once in 2014 and then again in 2020.

This season he's scored nine and assisted nine and Luciano Spalletti's side were in the Serie A title race until recently.
However, their hopes of a first league title since 1990 were dashed by a 3-2 defeat to Empoli last month.
AC Milan and Inter have pulled away at the top and the best Napoli can hope for is a third place and qualification for next season's Champions League.
Napoli were also knocked out of the Europa League by Barcelona in their play-off clash.

They return to action on Saturday afternoon against Torino.
