I wonder if he is from the same planet.

Over the past 20 years, it wasn't the only person who wondered if Roger was created by the tennis gods.

The greats are great athletes.

One of the few who could draw you in and grab your heart was the man who will retire later this month.

Some may have won more titles, but for many the once stroppy youngster was sport at its finest.

The Swiss legend gained fans unlike anyone before him because of his graceful strokes, precise serves and gentle waves to the crowd.

The 41-year-old learned how to play tennis at the Swiss National Tennis Centre.

He was a genius as a teenager, but also had a temper. He was punished for throwing the racket when he was 16 years old.

It may not have been a big deal when he was on the professional tour, but he still had a penchant for petulance.

He said it took him two years to find it. The fire to win but the cold to absorb losses. My career took off.

When he found that state, his game went through the roof.

After making his name as a 19-year-old by beating Pete Sampras at Wimbledon in 2001, and a year after the death of his influential early coach in a car accident, Roger Federer won his first of a record eight men's SW19 titles.

He won 11 of the 16 available Grand Slams in a four-year period in which he dominated the sport.

The gold-trimmed cardigans that the court wore were fully justified.

The next 11 years will see another eight Slams but the popularity of the man has been shaped by crushing lows.

The first came in 2008 when he was beaten in the Centre Court gloom by Rafael Nadal in the Wimbledon final, a five-set epic widely regarded as one of the greatest tennis contests of all time.

The Swiss broke down in tears when the Spaniard denied him a second time.

He said that this was killing him.

He was forced to give up his soul.

After winning the first French Open title of his career, he shed tears of joy.

That completed the career Grand Slam, a feat only five men had previously accomplished.

After three more wins, including a victory over an emotional Andy Murray at Wimbledon in 2012 it seemed as though his Grand Slam tally would remain at 17 as the first signs of serious injury began to appear.

The second golden period was just as remarkable as the first.

After six months out with a knee injury, he returned to win the Australian Open.

He won at the All England Club eight times and in Australia six times.

It will be intertwined with that of Nadal and Djokovic, who gatecrashed the Swiss' one-man party at the top of the men's game.

While struggling for fitness in the past three seasons, the Spaniard and the Serb have gone past his major tally.

For fans and sponsors, he has been the top choice.

He is one of the richest sports people in the world.

Serena Williams, who also announced her retirement last month, has excelled in other areas as well. They have dealt with it in different ways.

At Wimbledon this year, when he was given the most boisterous reception among a group of legends as part of Centre Court's 100th anniversary celebrations, he was cheered by spectators everywhere he went.

Two generations do not recall a sporting landscape without him.

Tennis will never be the same again, is a theme that has come from Nadal and others.

The next generation will have to follow in the footsteps of The Beatles at the festival.

The Swiss will return to the professional tour later this month in a tournament he helped create. It's not clear what standard he'll be able to reach since he hasn't played in a year.

Even if they only say one thing, tennis fans will still come to London.

Thanks for the memories Roger.
