Chelsea says a deal has been agreed with Fluminense to sign highly rated Brazilian right back Wallace in the January transfer window.

The European champions say the 18-year-old Wallace will remain with his Brazilian club until the next offseason.

Wallace, who will join fellow Brazilians David Luiz, Ramires, Oscar and Lucas Piazon at Stamford Bridge, is an under-20 international and considered one of Fluminense's most promising players.

Brazilian media have previously reported that Chelsea will pay about $7 million for Wallace.
