Ivan Ljubičić, Croatian tennis player
Ivan Ljubičić (Croatian pronunciation: [ǐʋan ʎûbitʃitɕ]; born 19 March 1979) is a Croatian former professional tennis player. He reached a career-high Association of Tennis Professionals (ATP) world No. 3 singles ranking on 1 May 2006. His career highlights include reaching a Grand Slam semifinal at the 2006 French Open, and an ATP World Tour Masters 1000 title at the Indian Wells Masters in 2010 as well as 3 other finals, 2 of them coming in 2005 at Madrid and Paris, and the other at the Miami Masters in 2006.

Since retiring, Ljubičić has coached ATP top 3 players Milos Raonic and Roger Federer. He was credited with Federer's improved backhand, especially evident on high shots, and tactical change of taking shots much earlier, taking more time, pace, and rhythm off his opponents at the same time making his overall game more offensive.
