"The Moroccan Magician" reached the quarter-finals of the Australian Open twice and the French Open twice. As well as the aforementioned nickname, some tennis analysts called him "The Moroccan McEnroe" due to his talent - he played with incredible touch, and often enjoyed the support of the crowd even when not at home. He led Patrick Rafter, winner of the US Open in 1997 and 1998, two sets to love during the first round of the latter tournament. In the third set he was upset with several line calls, telling umpire Norm Chryst to "get out of here", which sparked the beginning of Arazi's meltdown (and Rafter's comeback). During his career, he notably gained victories over former World No. 1s and Grand Slam champions Roger Federer, Andre Agassi, Yevgeny Kafelnikov, Marat Safin, Lleyton Hewitt, Juan Carlos Ferrero, Carlos Moyá and Jim Courier.
