South American champions Boca are due to meet Champions League winners AC Milan in Tokyo on December 14 to decide the unofficial world club champions.

But the exciting Tevez, 19, the inspiration when Boca won the Libertadores Cup for the third time in four years earlier this season, has also been included in the Argentina squad for the World Youth Championship in the United Arab Emirates.

Under Argentina Football Association (AFA) rules, the national team automatically gets priority. Boca have protested against the decision but a club spokesman said Tevez had gone to court on his own initiative.

"Boca did not make any complaint, Tevez did it on his own," the spokesman told reporters. "But, in any case, Boca support and approve everything the player is saying and doing."

Tevez is expected to be out of action with a knee injury for another two weeks but was asked to travel with the national team in any case. The World Youth Championship starts on November 27 and the final is due to be played on December 19.

The player was missing from the official Argentina team photo session on Monday and the squad left for the UAE on Tuesday without him, the AFA said.
