Former world number one Roger Federer is on the cusp of creating history on Sunday as he is set to take on Marin Cilic in the final of Wimbledon, which will be his 11th in the tournament.

The Swiss maestro has had a phenomenal year, starting with the triumph in the Australian Open, going on to register emphatic wins at the Indian Wells Masters, Miami Open, and Halle Open in the months that followed.

Coming into the Grand Slam event in London, Federer decided to skip the French Open, which he later explained was due to concerns about his longevity in the sport.

Missing the entire clay court competition gave him the ideal physical and mental preparation ahead of the Championship in the UK.

He showed glimpses of his former self as he outlasted each opposition right from the start and is yet to drop a set after the semi-final clash against Tomas Berdych, where the final scoreline read 7-6, 7-6, 6-4.

During the post-match interview on Friday, Federer gave an insight into his retirement plans and insisted there remains three major factors that are pivotal in him deciding when to call it a day from professional tennis.

Metro quoted the 35-year-old saying: "Health has definitely a role to play in my decision-making, no doubt about it. As I move forward, I’ll be very cautious of how much I will play, how much I think is healthy."

Federer and his wife Mirka have four children, and travelling with the entire family throughout the season will not be feasible at some point in the future, according to the world number five.

"Then, of course, it’s just discussions I always have, continuous discussion, with my wife about the family, about my kids, is everybody happy on tour, are we happy to pack up and go on tour for five, six, seven weeks. Are we willing to do that. For the time being, it seems like absolutely no problem, which is wonderful.

"Then success to some extent also is key for keeping – staying out there really. This tournament, again, helps me to stay hopefully on tour longer, to be honest."

Asked about 'till when he is foreseeing his future in the sport, Federer replied he is taking into account the form and fitness in his bid to determining the plan of action for the upcoming months.

"I haven’t made any decisions moving forward, how far, am I looking at the Tokyo Olympics [in 2020] or anything like that. I haven’t.

"Since the injury, honestly everything has been very much reset, that I just go sort of I’m planning till the end of the year, then I know what I’m going to play at the beginning of next year, so forth.

"Maybe I think a year ahead, but it’s just important to stay on track with the plan."

All eyes will be on the Centre Court this weekend as Federer is on the verge of securing his 19th career Grand Slam title and he is surely the favourite going into the tie against Cilic, thereby continuing his domination in world tennis on the back of an impressive campaign in the first half of 2017.
