Arsenal manager Arsene Wenger says he "certainly will not read" a book in which Manchester United counterpart Jose Mourinho is quoted as saying he would break the Frenchman's face.
Mourinho regularly clashed with Wenger while managing Chelsea, once describing him as a "specialist in failure".
"I talk about football - that's all I do," said Wenger, 66, on Friday.
"I'm not in a destructive mode, never. I'm more constructive. I am focused on Saturday's game against Chelsea."
Mourinho, 53, described Wenger as a "voyeur" in 2005, after his rival questioned Chelsea's transfer policy.
