Arsenal release four out of contract players

Arsenal have confirmed the departure of striker Yaya Sanogo after four years with the club.

Sanogo arrived from Auxerre in 2013 but failed to score a single league goal for Arsenal in 11 appearances. He also spent time out on loan at Ajax and Charlton.

The Gunners have also allowed academy players Stefan O'Connor, Kristopher da Graca and Kostas Pileas to leave the club.
