England international Walcott broke the existing record in 2009, hitting 40 metres in a nippy 4.42. seconds, claiming the crown from Gunners legend Thierry Henry.
However, it has now been revealed by 25-year old Walcott that someone has claimed the title from him, with Spain Under-19 international Hector Bellerin the recipient.
Speaking at a supporter Q&A session, Walcott was asked who would win a sprint between him and Henry - and he revealed Bellerin's new award in the answer.
Quoted on Arseblog, Walcott said: “Me! Thierry is in his 30s now so I would be very disappointed if I didn’t beat him. I beat his sprint record which Hector [Bellerin] has now broken.” However, the 36-time capped England international failed to reveal the timing of Bellerin's run, leaving people to guess how quick the Spaniard is.
Despite losing his record on the training ground, Walcott can still be happy in the knowledge that his career has progressed further than Bellerin, who has only tasted nine games worth of competitive football in his career - with eight of those games on loan at Watford.
His three month spell in Hertfordshire saw a series of solid performances in the Championship, and consistent displays of his evident pace, capped by registering one assist from the right-back position. Although the Hornets had extended the youngsters loan until the end of the season, Arsenal recalled their talent in February as cover for a series of first-team injuries.
Whilst it is impressive to have claimed the sprint title from one of the fastest men in football, it has long been proven that pace is not everything in top division football, and Bellerin looks as if he has a long way to go before he makes an impact upon the Premier League.
