There are high hopes for Hector Bellerin, the former Barcelona academy star who is getting chances in the Arsenal first team.
The right-back was touted as a future regular by Mikel Arteta this week, after coming in for the injured Mathieu Debuchy.
Still only a teenager, the Spaniard created a real buzz this year when it was revealed he had broken a club sprint record over 40 metres, held previously by Theo Walcott, regarded as one of the speediest players in the Premier League and world football.
Bellerin has been speaking about it for the first time, telling Arsenal's match day programme:
"It happened without anyone really noticing to be honest. We had run a 40 metre speed test and when I finished the conditioning coach came to me and said I broke the club record.
"Theo was walking by and I said 'Theo you've got competition this year.'
"I worked on the power in my legs so it was nice to see the work I'd been doing has given me extra pace. I'm sure Theo is going to come back faster when he returns from his injury so I've got to be on my toes.
"I wasn't expecting it really because I was just racing Chambo because he was in front of me. But we're footballers not sprinters so I'm not going to take it too seriously."
