Roy Keane has dismissed any notion that Chelsea are a great team as "nonsense".
Before tonight's Champions League last 16 clash with Paris St Germain, Chelsea manager Jose Mourinho said: "The hard work is to build a great team and we are a great team."
But Ireland assistant boss Keane, who branded Mourinho "disgraceful" last October when the Corkman was assistant boss at Aston Villa, claims that Chelsea have a long way to go before they can be classed as a great team.
"I think they have the potential to be a great team. He's clearly a great manager but they've got to back it up with some trophies," said Keane who was back on the TV tonight as a pundit for ITV.
"To say they're a great team at the moment is nonsense."
Paul Scholes, who was alongside his former Manchester United midfeld partner Keane for ITV tonight, agreed with the Irishman.
"Over four or five years you have to win trophies every year. It's a bit early to say they're a great team," said Scholes.
Meanwhile, social media has been busy discussing Keane's return to punditry.
