The forward beat club legend Thierry Henry's 40 metres record following his move from Southampton in 2009, but his own record has now been broken
Theo Walcott has is no longer the fastest player at Arsenal, with youngster Hector Bellerin having claimed his long-standing sprint record.
Walcott posted a time of 4.42 seconds over 40 metres following his move from Southampton in 2009, beating Thierry Henry's previous best of 4.82 seconds.
But the England international has now revealed that 19-year-old Bellerin has usurped him as the Gunners' sprint king, although he joked that he is never going to be overhauled by Henry.
Asked who would win in a race between himself and the club legend at an Arsenal fans' Q&A, 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.”
Bellerin made one apperance for the Gunners in the Capital One Cup victory over West Brom last season and spent a spell on loan at Watford.
