Porto gave themselves every chance of lifting the Emirates Cup after coming from 1-0 down to win 3-1 against Napoli.
Rafa Benitez clearly had his mind on the start of the season, leaving several key players on the bench.
Marek Hamsik, Gonzalo Higuain and Pepe Reina were all rested after their exploits against Arsenal yesterday.
Porto also rested a key player in the form of Jackson Martinez. The reasons for the exclusion, however, may not only be about fitness. The Colombian has been strongly linked with a move to the Naples side this summer and manager Paulo Fonseca may have decided not to tempt Napoli in to a move any more than they already are.
In an uneventful opening 45 minutes, the half-filled Emirates stadium was treated to a classic pre-sesaon friendly with both teams eager to save their legs for the start of the season.
Porto probed with their quick, short passing but a typically solid Italian defence left the teams in stalemate.
That was until a careless push on Gordon Pandev in the Porto box gave the referee no choice but to award a penalty - the fifth of the tournament so far.
Three of the previous four penalties had been missed but Pandev made no mistake and fired home from 12-yards to make it 1-0 to Napoli going in to the interval.
The second half saw the introduction of Napoli's star players. Both Hamsik and Higuain were brought on - the latter once again booed by the home crowd.
Despite the big names coming on for Benitez, it was Porto who returned from the break with more impetus. Their spell of pressure was rewarded when Nabil Ghilas was sent clear by Juan Quintero, and managed to finish past the goalkeeper Rafael despite appearing to fluff his shot.
That goal gave the Portuguese champions the confidence they needed and their dominance continued throughout the half.
Porto looked dangerous on the break and the pressure finally told as a cross from the right-side met the foot of the unfortunate Federico Fernandez, who scored an own goal to make it 2-1 to Fonseca's men.
That goal saw the undoing of the defence that looked so capable in the first half.
Defender Andrea Dossena made a pig's ear of a routine clearance in the 78th minute to gift Porto striker Lica the easiest goal he'll have this season.
The result sees Porto leap from bottom of the table to the top with the Emirates Cup awarding a point for each goal scored. However, Arsenal will only require any win against Galatasaray to claim the cup for the fourth time.
