The Denmark international claims that boss Arsene Wenger did not give him enough opportunities after he narrowly avoided serious injury in a car crash two years ago
The Dane, who spent seven years with the Gunners, completed a loan deal to take him to Wearside on the last day of the summer transfer window and now says he has no plans to go back.
He told The Sun: "I will never go back to Arsenal. If I can have it my way, I will never play for them again.
"After my car accident I never really got the chance to earn a spot in the first team.
"That is over one-and-a-half years with no real chance to prove myself."
The forward also spoke of relishing the challenge in playing for the Black Cats and promised to find a club to go to when his loan deal expired.
"I am really looking forward to playing for Sunderland and then we will see next summer," he continued.
"I will find a new club — but I will not go back to Arsenal, that's for sure."
