LISBON, Portugal (AP) -- FC Porto drew 2-2 at Benfica after a wild start that saw all four goals scored in a nine-minute span in the Portuguese league's most heated rivalry on Sunday.
Leader Benfica retained its three-point advantage over Porto, which has a game to play.
Porto struck first eight minutes in through defender Eliaquim Mangala when he headed in Joao Moutinho's free kick, but midfielder Nemanja Matic equalized for Benfica two minutes later with a long-range strike from a corner kick.
The game then quickly swung back in Porto's favor when Jackson Martinez scored in the 15th after dispossessing goalkeeper Artur Moraes of the ball and firing into the empty net.
But again, just two minutes later Nicolas Gaitan punched in a rebound to level for the hosts for good.
