David Raya is due to face old club Brentford this evening for the first time since permanently signing for Arsenal during the summer transfer window.

However, the goalkeeper is not the first man to play for both teams. While the Gunners' current number one was still a youth team player in Catalonia for third-tier club Cornella, one Wojciech Szczesny was making his debut for the Bees after joining them on a one-month loan in November 2009.

The then-teenage 'keeper saved a penalty from Wycombe Wanderers striker Matt Harrold - now Bournemouth's loan manager - in his second game while he conceded just three goals across his first six matches. Arsenal agreed to extend the arrangement for a further month and then again until the end of January.

However, the latter extension only came after Szczesny spoke to then-Gunners' manager, the legendary Arsene Wenger. "I got called back to Arsenal and told Arsene I wanted to stay," the 19-year-old explained. "He agreed for me to stay for another couple of weeks.

"I'm going to have another conversation with him about being here for the rest of the season.

"I'm enjoying it and it's great experience. I've got no real chance of being No.1 at the moment, so it's good to get regular football here."

A matter of days later, Arsenal announced that Szczesny would stay in west London until the end of May - while the goalkeeper made 28 appearances in total as Brentford finished ninth and 18 points adrift of the play-off places.

Szczesny returned to the Gunners that summer and made his Premier League debut the following campaign, establishing himself as the club's first-choice 'keeper after initially deputising for Lukasz Fabianski and Manuel Almunia. That would be the first of five years in the first-team.

Midway through the fifth, Brentford supporters voted Szczesny their goalkeeper of the decade!
