Max Dowman became the second-youngest player to play for Arsenal when he came on against Leeds

Arsenal's 15-year-old winger Max Dowman reminds Theo Walcott of Lionel Messi and is "so refreshing" to watch.

Dowman made his Gunners debut in Saturday's 5-0 Premier League rout of Leeds at the age of 15 years and 234 days, making him the club's second-youngest player.

And having watched the teenager in action, Walcott says his style reminds him of Argentina icon Messi - the ability to move quickly with the ball and use of a low centre of gravity to make defenders "tired".

"What's really fascinating is that [Arsenal manager] Mikel Arteta will allow him to do that because that's his strength," said Walcott, who spent 12 years at Arsenal after joining the club in 2006.
