THE Celtic players let their supporters down in the defeat to Zenit, according to Roy Keane.

The former Hoops and Manchester United midfielder branded Brendan Rodgers' side ‘bluffers’ after they fell to a 3-0 loss in St Petersburg that ended their Europa League involvement.

Celtic had impressed with a 1-0 first leg win in Glasgow last week, but Keane criticised the Scottish champions for failing to turn up when it mattered most.

"You are hoping Celtic can grind out a result to make the supporters proud, but they didn't do that,” he said to ITV.

"They needed to show courage. With 20 minutes to go and 3-0 down everyone wanted the ball ... bluffers.

"They never turned up really. We are always desperate for Celtic to 
stay in the competition because of their supporters.

"But they didn't do enough and show enough courage in possession. And 
they gave some shocking goals away.

"When you play this game you need to be brave. They played well last week but it's one thing playing well at home.

"You don't mind losing football matches but the way they lost will be 
hurting Brendan Rodgers."
