Arsenal legend Patrick Vieira says Arsene Wenger's legacy should never be underplayed.

When questioned about the current debate over Wenger's future, the 40-year-old adapted Barcelona's 'Mes que un club' slogan to suggest that Wenger has succeeded in revolutionising the club as Barca did in the days of Johan Cruyff.

"It's a difficult one, it's not just about Arsene but coaching in general. Now I'm into the other side I do understand how difficult it is," he told Copa 90.

"As a coach you're controlling the players you bring, what's going on on the pitch, the decisions you're making, but I think when players are on the field they have to take responsibility.

"It's really difficult to say 'Wenger in' or 'Wenger out' because I don't have all the information to make that decision, but it's important for players on the field to take responsibility because losing games - yeah, a manager is the first one - but at the same time, players have to look at themselves and see if they give everything for the football club.

"I don't think at Arsenal that every single player can say that they've been giving everything for this football club, for the shirt that they're wearing.

"The manager is always going to be the target, but you have to look at what Arsene did for the club in the last 20, 21 years.

"What the club was before and what the club is now. The club completely changed. It's more than a club now."
