There is nothing honest about what he says to the media.
He tells the media stuff that he has no intention of doing or stuff that he knows isn't going to happen.
He tells them,
"we are not afraid to spend"
"we can buy anyone"
"I will win the title within three seasons"
"judge me at the end of the season"
"it is only a short term injury"
"this team has mental strength"
"this team is capable of winning the PL"
"I know the weaknesses in our team and will strengthen?
"we are a big club"
"big clubs don't sell their best players"
"Cesc isn't leaving"
"RVP will stay"
"I nearly bought ?"
and many more.
He is not honest with the media, or the supporters.
He is a control freak that will; say anything rather than admit he was wrong.
At best he is naive with the media, but after being the longest serving manager in Europe, at a top club, you would have thought he might have learned from his many mistakes when dealing with them
This is one of Wenger's biggest faults.
He repeats the same mistakes almost every season, and doesn't learn from them.
Mbappe is the latest in an ever increasing line of top players that will turn him down because they, like the rest of us, can see what he is like.
