Brítez played in the 1999 FIFA World Youth Championship in Nigeria as well as the 2001 FIFA World Youth Championship in Argentina. There, he was spotted by officials from a Spanish club and moved on to Europe but never fulfilled his potential there ultimately returning to his native Paraguay. Stints abroad in Israel and Portugal did not bear any fruit for Brítez' career for the second time so he returned to Paraguay. On 30 August 2010, he signed with the Superleague Greece club Panserraikos F.C.. According to Paraguayan media, tired of the abuse and conflict between managers, coaches and players of Panserraikos F.C., Brítez terminated his contract with Panserraikos F.C. on 25 October 2010 and returned to Paraguay. Another website stated that Jorge Britez returned to Paraguay after annulling Panserraikos contract. Britez's agent Miguel Gonzalez Zelada explained that "With Britez we arrived at an agreement with the Greek club to cancel the contract, since he has not adapted, he does not like the treatment he received from the directors and the management. Now we are going to see where he can train, and by the end of the year find a club to play at,".
