London, Nov 8 (IANS): Serbian Novak Djokovic has congratulated his successor Andy Murray after the Scotsman dethroned him as the World No.1 men's tennis player.

Djokovic was removed from the No.1 spot for the first time in 122 weeks.

"Congratulations Andy Murray! Very well deserved and hard fought milestone," Djokovic wrote on his Facebook page on Monday.

Murray claimed the top spot last Sunday (6 November) by winning his eighth title of the year at the Paris Masters.

His elevation ensured he will be the top seed in the season-ending World Tour Finals in London.

Djokovic began the year strongly with wins at the Australian Open and the French Open but has suffered an alarming dip in form recently.

It allowed Murray to take advantage of his form loss and claim the summit spot in the rankings.

Djokovic praise Murray for his relentless pursuit but said he is looking forward to the November 13 starting London tournament to regain his form.

"Your dedication and passion has paid off, and I am really happy to be in the same era with you! As to all my fans, thank you for being there for me. I am working hard and will see you all in London! I am always game when it comes to good challenges and final 8 is exactly that. See you in a few days," he wrote.
