Seventeen-time Grand Slam winner Roger Federer has tipped his cap to Britain's newly crowned world number one by posting a congratulatory tweet for his fellow tennis professional.
Federer, who spent 302 weeks on the sport's top spot himself - which is a record - posted this message: "We have a new [crown emoji] in town. Congrats Sir @andy_murray."
Murray's number one status was confirmed when Milos Raonic withdrew from the Paris Masters semi-finals through injury, giving Murray a pass to the final.
This ensured that the 29-year-old will have more points than the now ex-number one Novak Djokovic when the new ATP rankings come out on Monday.
Murray only had to make it to the final of the Paris Open so he will leapfrog Djokovic regardless of whether or not he wins against John Isner on Sunday.
Among a whole host of personalities within the tennis world to hit social media sites with praise for Murray was his mother Judy, who tweeted a picture of her with her son as a youngster on the tennis court. The caption read: "You've come a long way, baby."
Ever since he first broke onto the professional scene the Scotsman has always told media reporters that his ultimate dream was to reach the highly coveted world number one spot.
And now, after occupying the number 2 rank for an astonishing seven years, his dream has finally been realised.
Murray first turned pro in 2005 aged 18. Since that time he has won a gargantuan number of 42 career men's singles titles.
Among his vast array of personal honors are three Grand Slam titles, with two of those coming at Wimbledon, Olympic golds at London 2012 and Rio 2016, and one Davis Cup.
Murray became the first British player to win the U.S. open since 1977 - and, in fact, the first British man to win a Grand Slam singles event since 1936 - when he beat Novak Djokovic in the 2012 final of the event.
The last British Man to win a Grand Slam title before him was the legendary tennis and fashion icon Fred Perry.
It was a feat that earned Murray a third-place trophy in the BBC Sport's Personality of the Year awards.
