Outspoken former Manchester United star has hit out at the Blues again
"For me, there has always been a falseness about the Chelsea squad.They seem at pains to show how together they are, but it all looks so staged," he wrote in his regular Sun on Sunday column.
The former Irish skipper blasted the Blues as 'childish' for their ear flicking antics before the Birmingham City victory. Keane said a better way to show team spirit would be to overturn the 3-1 deficit to Napoli on Wednesday night.
Keane also suggested that Andre Villas-Boas had made mistakes during his brief tenure at Stamford Bridge by isolating Nicolas Anelka and Alex.
"As a manager, you have to keep your senior players onside because there will be weak individuals who will fall in with what they think.
"By all means leave them out, but if you do then you need to show them respect with one-on-one chats and I'm not sure if AVB did that.
He added: "He also suffered from the fact he worked at Chelsea before as a scout. If that's how a player sees you, it can be hard to change."
The pundit had little sympathy for the Portuguese's sacking saying 'football doesn't work like that' and added that Roman Abramovich got it wrong by firing Carlo Ancelotti last May.
"The sacking of Carlo Ancelotti a year after he won the double doesn't look too clever now. This was a man who had experience at AC Milan, a far bigger club than Chelsea."
Chelsea face Napoli on Wednesday night at Stamford Bridge under caretaker manager Roberto Di Matteo.
