The 29-year-old shot-stopper played in the 2008 final, when the Blues missed out after losing to Manchester United on spot-kicks after a 1-1 draw.
And even though he is confident Roberto Di Matteo’s side will be able to win inside normal time at the Allianz Arena, Cech has revealed he has been watching footage of Bayern’s previous penalties and so knows exactly what to expect.

“I’ll have all the information I need for a penalty shootout but I think this will be decided in 90 minutes,” he said.
“I’ve been watching the tapes of Bayern’s games. I’ve seen everything I can but in the end it’s all about the moment and whether the penalty taker is strong enough to keep calm and place it well.
“If he does that then the keeper has no chance, so in a shoot-out you try to force people into mistakes.
“In 2008, we had plenty of information about Manchester United penalties. We’d lost to them in a shootout before but you can’t always rely on what you’ve seen. You need to rely on your instincts.
“We had 120 minutes and penalties to win the cup but it didn’t happen. You can’t change history.
“Crying because I lost a match is not my style. You can only change the present and the future — and now we will have another go.”
A £7 million signing from French club Rennes in 2004, Cech will turn 30 on Sunday and he admitted he would love to celebrate the landmark on a victory parade in west London.
“If I get a cup, I don’t need a cake,” he said.
