The two head into Sunday’s final with the 35-year-old Federer having beaten his 28-year-old opponent in six of the seven times they have played each other in the past.
In last year’s Wimbledon quarter-final match between the two, Cilic lost in a close five sets to the Swiss 18-times grand slam winner, who needed to save three match points for the victory.
Cilic feels he has the ability to go one better in today’s final and upset Federer’s plans on claiming a record breaking eighth All England Club men’s singles title.
“I was one point away from winning a match over here against him. Definitely, I believe in my own abilities to get through and to win it,” the 28-year-old said.
“But I still know that it’s a big mountain to climb. Roger is playing maybe some of the best tennis of his career at the moment, having a great season.
“So I know it’s going to be a huge challenge. But I believe I’m ready,” he added.
Federer starts today’s final as the clear favourite having not dropped a set so far at SW19.
