Gilberto Silva has warned Arsenal could face the same malaise as Manchester United when Arsene Wenger leaves the club.
The former central midfielder, part of the 2003-04 Invincibles, is disappointed at the continued criticism of Wenger, whose contract runs out at the end of this season.
Silva suggested Arsenal supporters might be in for a shock once Wenger departs, claiming they only need to look at United's demise after Sir Alex Ferguson's retirement.
'Arsene at this time is facing a lot of criticism for the way the team play and they haven't got the trophies,' Silva said.
