Chelsea FC gave José Mourinho the victory he wanted over his former club, with Aleksei Smertin, Didier Drogba and John Terry scoring the goals to leave the English team with a maximum haul of six points from their two UEFA Champions League Group H fixtures.
In contrast FC Porto have just a single point from two games, and the memory of their glorious triumph in last season's competition, masterminded by Mourinho, is starting to fade. This was their first loss in 13 Champions League ties and they can have no complaints.
Both teams began with changes to their Matchday 1 lineups. One of three Chelsea alterations left Damien Duff in place after a successful return at Middlesbrough FC last weekend following an injury lay-off, with Smertin also stepping in. Ricardo Carvalho's selection meant that both Mourinho's summer captures from Porto were in the starting eleven. Before kick-off the centre-back was presented with the 2004 UEFA European Football Award for Best Defender.
Porto coach Víctor Fernández made four changes as Hélder Postiga dropped to the bench and Luis Fabiano and Derlei started. Both first-choice full-backs Giourkas Seitaridis and Nuno Valente missed out through injury with Bosingwa and Ricardo Costa taking over.
Duff was crucially involved as Chelsea got off to the kind of start that Mourinho had dreamed of. Eidur Gudjohnsen weighed up the options, and while his forward pass did not quite find its target, the Icelandic striker continued his run and was found by Duff's cleverly scooped pass. Gudjohnsen's cross was volleyed in by Smertin.
Chelsea continued to press with only a hopeful attempt by Luis Fabiano advertising Porto's initial intent to get back into the tie. Drogba and Gudjohnsen were picked out with ease and that did not bode well for the visitors who were relieved when they managed to get bodies in the way of a couple of thunderbolts from Frank Lampard.
Gudjohnsen's appetite was impressive and he frequently came deep in search of the ball. He staggered on through two tackles on the edge of the penalty area and found himself in a good shooting position but pulled his effort wide.
Porto enjoyed more possession as the first half closed and Ricardo Costa was able to take advantage of the space ahead of him down the left. At the first hint of serious alarm Carvalho was there to tidy up, but Luis Fabiano did get behind the Chelsea defence for the first time on 43 minutes, chipping the ball across Costinha who, at full stretch, was unable to connect.
Drogba nearly scored at the start of the second half, heading a Lampard free-kick just too high. And when Duff curled over another set-piece in the 50th minute, Drogba, drifting away from his markers, this time found the target with a back-header.
Porto introduced Carlos Alberto and Benni McCarthy in a bid to add some new zest to their attack and the South African nearly did just that, turning sharply in the area before extending Petr Cech with a low shot. In the 68th minute the two substitutes combined to give Porto some hope, Carlos Alberto's shot taking a slight deflection off the head of Terry which left Cech in trouble. Although he got a hand to the ball, McCarthy was there to take full advantage of the rebound.
Yet Chelsea needed only two minutes to restore their two-goal advantage, Terry heading in Lampard's free-kick to ultimately confirm victory.
