Porto take the lead on Chelsea with rebound volley

That’s Yacine Brahimi turning Branislav Ivanovic inside out before forcing Asmir Begovic into a good save, and Andre Andre sitting in a huge bubble of unmarked space in the penalty area to volley in the rebound. Why Chelsea were letting a Porto attacker just sit there with no one paying attention to him we’ll never know, but they certainly will be regretting that for awhile.
