Moussa Marega grabbed a brace as Porto moved to the top of the Primeira Liga table after defeating Boavista 4-0 in Tuesday's encounter.
The commanding win at the Estadio Do Dragao moved Porto to 67 points after 28 matches with a three-point lead above second-placed Benfica who lost a seven-goal thriller earlier in the evening.
After a goalless first-half, Marega started the party for the hosts with his opening goal in the 53rd minutes and Alex Telles doubled the lead seven minutes later from the penalty spot.
Sergio Oliveira made it 3-0 from the penalty spot again in the 70th minute before the Malian striker's second goal six minutes from full-time was the icing on the cake for Porto.
