Petr Cech has revealed he will rely more on guesswork than homework should Chelsea's FA Cup final with Liverpool go to penalties.
The Blues have been practising spot-kicks in the build-up to this afternoon's Wembley showpiece, with goalkeeper Cech having also studied videos of the Reds' previous shootouts.
But he admitted all that could go out the window should the match ultimately go the distance.
"I've seen everything I can," Cech said. "It's all about the moment and if the player is strong enough to keep calm and place it well.
"If he does, you have no chance so, in a shootout, you try to force people to make mistakes.
"I don't know in advance which way I'm going to dive. The procedure comes in the last few seconds before he takes the penalty.
"I might be persuaded to go to the right before the game and then change my mind completely by the way he prepares to take his penalty.
"You can't always rely on what you've seen. You need to rely on your instincts."
"I've won three FA Cups and it would be great to have a fourth," he said. "It's always special to win the FA Cup."
It would be even more special to win the Champions League a fortnight later but Cech would not trade one trophy for the other.
He joked: "The FA Cup is so small it can fit inside the big one."
