Arsenal could face disaster if Ozil and Sanchez leaves. Roy Keane

Roy Keane has urged Arsene Wenger to get Mesut Ozil and Alexis Sanchez to sign new contracts at Arsenal because it would be a 'disaster' if they don't.   Ozil bagged his first hat-trick for the Gunners and Sanchez scored with a sublime chip as Arsene Wenger's side thrashed Ludogorets 6-0 in the Champions League on Wednesday night. The pair also registered an assist each as they both continued their excellent form that has helped Arsenal to second in the Premier League on level points with Manchester City.

 Arsenal also tops up their Champions league table with goal difference against PSG both seating at 7 points each after 3 games.
