The Swiss wins record-extending 19th Grand Slam crown thanks to 6-3 6-1 6-4 win .
With Andy Murray, Novak Djokovic and Rafa Nadal all having fallen by the wayside at Wimbledon this year, Federer took on big-hitting Cilic in the Centre Court showdown in front of watching dignitaries.
The Croatian was being forced to dig deep as he looked to get his feet moving, but was still making far too many unforced errors in order to keep pace with Federer, 23 days before his 36th birthday.
With the threat of rain on the horizon, Federer closed in on an historic title by breaking for a 4-3 lead and completed his mission by serving the match out with his eighth ace to join Bjorn Borg as the only players in the Open era to win Wimbledon without dropping a set.
"I gave my best. That's all I could do," Cilic said. "I never gave up when started a match. That was my idea today. That's what I did throughout my career.
"I had an amazing journey here. I played the best tennis of my life. I really want to thank my team, they gave so much strength to me. It was really tough today. I'm definitely hoping I will come back here (to the final) one more time."
