Chelsea's poor start to the season continued as they were beaten by Porto in the Champions League.

Andre Andre gave Porto the lead, volleying in after Asmir Begovic pushed away Yacine Brahimi's effort.

Midfielder Willian equalised on the stroke of half-time with a superb free-kick from the edge of the area.

Maicon put the home side ahead again with a flicked header at the front post, before Diego Costa rattled the bar with a curling shot.

Chelsea's Cesc Fabregas and Pedro both forced Spain team-mate Iker Casillas - making a record 152nd appearance in the competition - into saves early on.

But despite their early pressure, and a late penalty claim for a handball by Ivan Marcano, they came away from the Estadio do Dragao with nothing.

Problems at the back

Andre Andre goal graphic

Yacine Brahimi (8) caused Branislav Ivanovic (2) plenty of problems and skinned him for the first goal

Chelsea boss Jose Mourinho sprung a surprise before kick-off by leaving out last year's PFA player of the year Eden Hazard, who has struggled for form this season. On-loan striker Radamel Falcao failed to even make the bench against his old side.

Meanwhile, Brazilian midfield duo Willian and Ramires - who both came on and scored in the 2-2 draw against Newcastle at the weekend - were named in the starting side, as was striker Diego Costa, currently serving a domestic suspension.

But it was in defence that the Blues looked to have the biggest problems when the Portuguese league leaders went ahead six minutes before half-time. Full-back Branislav Ivanovic's problematic season continued when he was too easily beaten by Algerian Brahimi in the lead-up to Andre's goal.

Mourinho described his side's first-half performance against the Magpies as "minus one out of 10" and this tie looked to be heading the same away until Willian levelled with a curling free-kick.

Chelsea have conceded the second most goals (14) in the Premier League this season, and Jolen Lopetegui's Porto underlined the London club's problems at the back as Maicon lost his marker to reach a near-post corner and head past Begovic's front post. Danilo also hit the post from another set piece.

Mourinho magic wearing off?

Toiling in 15th place in the defence of their Premier League title, eight points behind leaders Manchester United, Mourinho's side have now suffered five defeats in 11 games across all competitions this season.

The Portuguese manager has had disagreements with the media and differences with his coaching staff as his team have stuttered so far domestically, and Mourinho's troubles appeared to have poured over into Europe.

Mourinho's side easily defeated Maccabi Tel Aviv 4-0 in their opening group game and Chelsea might have taken a point from a hardworking Porto side.

But they saw efforts either hit the woodwork or deflected wide, while Marcano appeared to handle the ball in the area, as Mourinho, who has won the competition with Porto and Inter Milan, saw his team defeated at his former club.

Man of the match - Yacine Brahimi

Yacine Brahimi

Algerian midfielder Yacine Brahimi gave Blues full-back Branislav Ivanovic a torrid evening with his pace and trickery. In defence, he also won the ball back nine times, the joint-most of any Porto player

'Two ridiculous moments cost us'

Chelsea manager Jose Mourinho: "We watch dozens and dozens of repetitions of Porto taking corners. We were completely ready for that and in a moment when the game is under control we concede a goal that is ridiculous.

"They hit the post from a similar mistake. Apart from that, the game was balanced. Two ridiculous moments and we were punished."

Porto coach Julen Lopetegui: "The players attitude was amazing, spectacular. It was our best performance of the season. I have to congratulate my team. This three points are totally deserved. It was tough and unfair to go to the dressing room at half-time with a draw, but we reacted well."
