Roger Federer has parted ways with coach Stefan Edberg.
The former world No.1 will now work with Croation Ivan Ljubicic.
Ljubicic retired from professional tennis in 2012 and reached a career high ranking of No.3 in the world in May 2006.
"After two year successful years, I would liek to thank Stefan Edberg, my childhood idol, for agreeing to join my team," Federer said in a statement on his official Facebook page.
"Although it was supposed to only be for 2014, Stefan was great and agreed to extend the partnership through this year which I really appreciated. He taught me so much and his influence on my game will remain.
"Severin Luth, who I have been working with since 2008, will continue to be my main coach and he will be joined by Ivan Ljubicic."
