Carlos Tevez scored a match-winning double in what could be his last Superclasico as Boca Juniors won a thriller 4-2 at River Plate.
The Argentina international is considering a move to the Chinese Super League, with Shanghai Shenhua hopeful of signing him in a big-money deal, and has also suggested he could be set to retire.
But Tevez cemented his Boca legacy with a vital double as his side came from behind to win against their fierce Buenos Aires rivals.
Both of last season's Primera Division derbies had finished 0-0, but there was much more drama this time around.
