Brazil captain Cafu has said he is undecided about joining Yokohama F-Marinos this July despite reaching an agreement with the J-League club at the start of the year, a Japanese newspaper reported on Sunday.

The 32-year-old was set to move to Yokohama for $3.5 million at the end of his current contract deal with Italian Serie A club AS Roma.

But the move was apparently thrown into confusion after comments Cafu made in an interview on Italian television over the weekend, according to the Nikkan Sports daily.

"I haven't decided yet. I will wait until the end of the season. I haven't signed for anybody as things stand now," Cafu was quoted as saying.

Yokohama officials announced in January that Cafu would become an F-Marinos player on July 1. The defender was understood to have signed a contract for two-and-a-half years.

Cafu led Brazil to a fifth World Cup triumph in Japan and South Korea last June. The South Americans beat Germany 2-0 in the final at the International stadium.

But whether or not Cafu will appear at the World Cup final venue on a regular basis for Yokohama now appears less than certain, especially with Serie A club AC Milan said to be interested in signing him.
