Arsenal defender Hector Bellerin has signed a long-term contract extension to end speculation over his future.

The Spain international, 21, had been heavily linked with a return to former side Barcelona, while Pep Guardiola was reportedly interested in taking him to Manchester City.

The agreement for Bellerin comes as a major boost to Arsenal, who are also locked in renewal negotiations with star players Mesut Ozil and Alexis Sanchez, both of whom are out of contract in 2018.

Bellerin joined Arsenal's academy from Barca in 2011 and made his debut in September 2013.
