Wenger stated that Wilshere will start against BATE Borisov, and he did not seem too bothered with the ice skating pictures.
"I'm always (honest). I thought really that he wouldn't play, that's what I had been told".
That effort was ultimately in vain as the Gunners went down 3-1 in a thriller but the former Lyon star's presence lingered with Mourinho as he accused Manchester City boss of being similarly underhand by claiming playmaker David Silva is a doubt for Sunday's Manchester derby.
"I'm telling the truth", Mourinho said when listing the availability of some of his players.
The France worldwide was a shock inclusion in the 3-1 defeat to the Red Devils after Wenger had categorically stated he would miss the game after limping out of the midweek victory over Huddersfield at half-time.
"I am here to fight as long as I can, as long as mathematically it's possible you have to fight, you cannot give any other message out". But he was fine and that's football'.
Wenger insisted that his rotation policy had been beneficial for all, especially on the injury front as it meant all of his players had clocked up minutes.
Defender Shkodran Mustafi would not have been involved even if he had not been forced off early on in the defeat to United.
"He works very hard to come back into it", Wenger said. "One of the positives is that the behaviour of the squad is remarkable and impeccable".
"It is not ideal for your balance, the way you fall down, for a footballer it's not great", said the Frenchman.
Petit won the double with Arsenal in 1998.
Wenger has never been a fan of parachuting third place teams into the lesser competition but had rarely had to worry about it. "We voted many times - that is what you call democracy".
