ASM Clermont Auvergne coach Vern Cotter is expecting the biggest game of the year when former Heineken Cup Champions visit Stade Marcel Michelin on Sunday.
The Tigers sit a place and two points above Clermont in Pool 4, but Cotter is hoping for a repeat performance to the one that downed the Tigers 40 v 30 at the same stage of the competition two years ago.
"We are expecting the biggest game of the year in terms of intensity," said Cotter.
"We must be prepared and ready from the kick-off and our control must be there.
"We know we have to stay focused and we have worked well as a group all week and are ready for the game.
"Leicester are a strong side and we know that they will be coming here with the intention to play some good rugby and will be looking for the win.
"We can't sit back and wait for them to come at us we have to start well.
"They were surprised when they came over here two years ago and we got the win but this time they know all about us and will be expecting a big clash."
