Disagree that Wenger is not ruthless.. when time came to pull the plug, AW pulled the carpet beneath the floors of some players quicker than you can blink an eyelid- Vieira, Lauren, Gilberto, Eduardo etc
Where I think AW seems less ruthless is because of Rosicky, Diaby, Ramsey. These players and some more are here more because of Arsene's stubborness rather than him being less ruthless!
