4) How many incidents had he actually seen but lied about?

How many times have we been infuriated by Wenger’s comments in post-match interviews? Incidents that changed the game, incidents that disgraced the game, incidents that would make any manager sweat over how he can explain it all away?
No, Wenger was (and still is) the master of deflecting questions and it frustrates journalists and pundits alike when they cannot comment on his thoughts about key events in the game.
The French manager has admitted before that he does protect his players in the media. It was a ploy he used especially in the first few years at the Emirates when youngsters needed to be shielded from the cut-throat world of public criticism. And he made it a point to never bring up any particular player’s errors and dwell on them, preferring to deal with it privately.
“Sometimes I see it but I say that I didn't see it to protect the players and because I could not find any rational explanation for what they did.” – Wenger in 2009.
But there are so many incidents that he clearly must have seen? Per Mertesacker’s red card tackle on Diego Costa? Alexis Sanchez’s handball goal against Hull? The planes that carried the ‘Wenger Out’ banners this season?
How many had he seen?
