Versatile midfielder Francis Coquelin has signed a new long-term contract with Arsenal.
Coquelin, 20, has played 12 games for the Gunners this season after spending last season on loan at Lorient. It is believed he has signed until 2015.
A statement on the Arsenal website read: "Demonstrating his versatility with a string of fine performances in both holding midfield and defence, Coquelin has established himself as a valuable addition to the first team squad this term, putting in a man of the match performance against Tottenham in October and providing excellent cover in both full-back positions.
"Everyone at Arsenal looks forward to Francis' continued contribution to the Club in the years to come."
As well as being a regular for the Reserves in recent seasons, Coquelin was an integral part of the FA Youth Cup-winning side of 2009 and a key member of the France team to win the European Under-19 Championships a year later.
