Chelsea scored a 1-0 win at Sporting Lisbon in the Champions League and inflicted a home defeat on the Portuguese side for the first time in four years of European competition.
In a match where both teams showed relentless attacking intent, Nemanja Matic's goal in the 34th minute gave Jose Mourinho's team victory against their Group G rivals who had been unbeaten in their previous 16 matches in Europe at the Alvalade Stadium.
Mourinho, returning to Sporting two decades after starting his coaching career there as an interpreter, could have enjoyed a more comfortable night if not for an impressive display from the hosts' goalkeeper Rui Patricio.
The victory took Chelsea to the top of the table on four points, with fellow Group G rivals Schalke 04 being held to a surprise 1-1 draw at home to Maribor.
38-year-old Francesco Totti became the oldest scorer in European club competition history when he netted in AS Roma's 1-1 draw at Manchester City in their Group E match.
