Gibbs made his first-team debut in the 2007/08 campaign and last season the 19-year-old continued to demonstrate his talent with 21 appearances for the Gunners.

The left-back's form earned him a place in the England Under-21 squad for this summer's European Championship, where he helped his nation reach the final.

Arsenal have now rewarded Gibbs with fresh terms, and manager Arsene Wenger has hailed the youngster's progress.

Wenger told the club's official website: "Kieran made such a great impact last season and the progress he made throughout the year was fantastic.

"Kieran is an intelligent player with huge quality and he proved last season with his performances that he has great potential.

"We're delighted that Kieran has committed his future to Arsenal and we're all excited to watch his future development at the club."

Gibbs follows Theo Walcott, Lukasz Fabianski, Aaron Ramsey and Jack Wilshere, in signing new long-term extensions with Arsenal.
