Arsenal striker and World Cup winner Lukas Poulsen has the key to his locked doors and he hopes to use it to unlock the door to his apartment.

Poulsen’s apartment in London has a door locked with a key and has a number on the door, which is linked to the address.

“I’ve just received a text message saying ‘Lukas is locked in his room and I need to get in there’,” Poulsens brother David told BBC Sport.

“It’s been a little while and I’m in London and we’re getting used to the idea that we’re going to have to leave the city.”

Poulssen is on the verge of joining his new team-mates in London for a training camp and his team-mate Tomas Rosicky is also due to arrive on Thursday.

David said the message was an interesting twist to the game.

“He’s a bit of a football nut and he knows how to get a key to the door.

He knows how the locks work, so he has a pretty good idea how they work,” he said.”

And he knows the locks in the building in which the team is based, so we’re just going to need to work together to get it done.”

Poulssen’s agent, Thomas Ellinghorst, confirmed he would contact the players if the key was needed.

“Lukys has already had the lock installed and we are happy that he is staying with us and is staying in London,” Ellinghorn said.

“We have a good relationship and he has the support of the club.”

David Poulsson and Tomas Rosicki were part of the squad which won the Champions League in 2013 and 2014.

The pair will join Arsenal for the preseason after a season-long loan.
