Theo Walcott has challenged Arsenal teammate Hector Bellerin to a sprint race to determine who is the quicker.
Spanish right-back Bellerin, 20, is renowned for his pace and earlier this year broke Walcott's 40m sprint record in a time of 4.42s.
Taking over Arsenal's Snapchat account this week, Bellerin posted a video in which he jogged past Walcott and declared "Look, I'm quicker than Theo!"
The 26-year-old forward later replied with a video message asking his teammate to settle the debate once and for all.
