Another Oxlade-Chamberlain could be set for stardom.

Arsenal star Alex Oxlade-Chamberlain's 13-year-old brother Christian has joined Portsmouth's academy.

"I've been and watched him a few times and it's good to see him improving," Alex told Arsenal Magazine. "He's got a good physique too. He's five years younger than me and already my height.

"He plays on the wing sometimes but my dad reckons he might end up as a holding midfielder. He's big, physical and likes to pass the ball."
