Just googling it would have sufficed.

In the English version of the manga, or as translated directly in a chapter of the Japanese manga, it is "You still have lots more to work on." In the English anime, it is translated as "You still have a ways to go." He says this to annoy and also to taunt his rivals. While most often linked to Ryoma Echizen, it is actually a derogatory phrase that is heard quite often in anime.
