Maicon scored the winner as FC Porto beat Chelsea 2-1 in the Champions League on Tuesday and heaped more misery on Jose Mourinho’s team.
Yacine Brahimi helped put Porto ahead in the 39th minute when he beat Branislav Ivanovic on the left, and goalkeeper Asmir Begovic could only push away his shot as far as Andre Andre, who volleyed into the net.
Willian equalized with a curling free-kick in first-half added time before Maicon put Porto back in front with a glancing header at the front post in the 52nd.
It was a dismal return to his former club for Mourinho, whose career took off when he coached Porto to the Champions League title in 2004.
Chelsea lies 14th in the Premier League after an unhappy start to the season.
