Arsenal legend Thierry Henry has been labelled a "pain in the backside" by former team-mate Lauren.
The Cameroonian full-back was part of the Invincibles team led by clinical goalscorer Henry in an unforgettable 2003/04 campaign.
Lauren has revealed how a fierce competitive edge throughout the team helped drive them to a historic Premier League season without tasting defeat.
And he's pinpointed Henry as a particularly feisty character who was not fun to compete against on the training ground.
"We were living 100% football," he told BBC Sport . "On the training ground, everyone wanted to be the best - when they picked two sides, no-one wanted to be the referee.

"It was competitive with any discussion about anything - we were arguing about everything.
"Thierry Henry was a pain in the backside; it was unbelievable."
Lauren also recalled a story when feared defender Martin Keown broke the leg of one of his own team-mates.
It was a move which caught the attention of one team-mate in particular and convinced him to start wearing extra protection.

"I remember there was a challenge by Martin Keown on Rami Shaaban - his own goalkeeper - and, unfortunately he broke his leg.
"I remember Gilberto Silva was there and he came up to me and said: "Aqui, estan todos locos?" ("Are they all crazy here"?)
"The next day, and for every single training session after that, Gilberto wore shin pads - just in case.
"But apart from that one specific incident that was unlucky, we were all committed, all competitive but good honest, noble, people."
