Oscar De La Hoya just signed Ryan Garcia to a new contract -- but he's gunning to get Garcia even MORE money ... telling TMZ Sports he wants to make King Ryan the first boxer to sign a $700 MILLION deal!!!
21-year-old Garcia -- who's already racked up an impressive 18-0 record -- clashed with Oscar over the weekend, claiming Golden Boy Promotions has failed to get him the big money fights he feels he deserves.
There were rumblings Garcia was looking to split from Oscar -- but after they agreed to an extension, it's clear the beef is squashed.
