Arsenal were beaten on the final day of the Emirates Cup by French side AS Monaco on Sunday.
Monaco scored the only goal of the game in the 37th minute when Jack Wilshere brought down Dirar outside of the penalty box.
Joao Moutinho floated in the free-kick and an unmarked Radamel Falcao, who has only just returned from injury, headed the ball past the Arsenal 'keeper to score.
Arsenal didn't really test the Monaco defence at all during the first half. Olivier Giroud was caught by the offside trap on multiple occasions and Arsenal wasted their set-pieces to keep the score at 1-0 at the half.
The second half provided little solace for Arsenal. The Gunners were robbed of a clear penalty when Gedion Zelalem played in Chuba Akpom and the striker was taken down by Monaco 'keeper Danijel Subašić in the box.
The referee pointed to the spot but the linesman thought Akpom was fouled just on the edge of the area and the referee then changed his mind and awarded the free-kick.
Wilshere also came close to scoring after Santi Cazorla played a brilliant back-heel to the Englishman but Subasic reacted brilliantly to deny him.
The result meant that Valencia won the Emirates Cup after the Spanish side bear Benfica 3-1 in the earlier game of the day, putting them just a point ahead of Arsenal.
Arsenal next play on Sunday against current Premier League champions Manchester City in the annual Community Shield at Wembley Stadium.
