Porto striker Jackson Martinez says that there was a "special flavour" to enjoy after his goal brought Benfica's long unbeaten run to an end.
The Colombia international rose highest to power home a header in the first half of his side's Taca de Portugal
semi-final first leg on Wednesday as Porto stole the bragging rights in the latest Portuguese Classico.
Benfica had not lost a game since their Champions League defeat to Olympiakos during the group stage and, with Portugal's giants set to face each other in the league, League Cup and second leg of the semi-final - as well as a possible meeting in the last four of the Europa League - Martinez knows the importance of the result.
"We know Benfica are very strong. We had to begin decisively and put into practice what we had been working on," he told Sport TV. "We're all doing a great job, the coach above all.
"Benfica did their bit but we played a great game. We fought, we ran and we helped each other. When it's like this, the victory has a special flavour.
"Now we have to think about the next game. The 1-0 gives us an advantage but we have to prepare for the second game as well."
Porto face Nacional on Sunday before their Europa League encounter with Sevilla, with the second leg of the cup clash set for April 15.
