The Gunners boss has come under serious heat following the north Londoners recent run of poor form.
Four Premier League losses from their previous five games has seen Arsenal drop to sixth in the table.
And things boiled over in the away game against West Brom when Gunners fans flew over two planes with messages both for and against Wenger.
In a recent interview with Copa 90 , Arsenal legend Vieira had his say on the matter.
“It’s not just about Arsene,” said Vieira. “It’s about coaching in general because now I’m on the other side I understand how difficult it is.
“You’re controlling the players, what’s happening on the field, the decisions you’re making.
“But I think when players are out on the field they have to take responsibility.
“It’s difficult to say ‘Wenger In’ or ‘Wenger Out’ because I don’t have all the information to make a decision and it wouldn’t be fair for me to make a decision.
“But it’s important for players on the field to take responsibility because when you lose games players have to look at themselves.
“At Arsenal I don’t think the players can say they have been giving everything for the club.
“The manager is always going to be the easy target.
“You have to look at what Arsene has done for the football club over the last 20 years – what the club was before and what it is now.
“The club has changed, it’s more than a club now.
