Chelsea's poor start to the Premier League season continued as Ollie Watkins' fine strike saw Aston Villa to a 1-0 win against the 10-player Blues.
It is the first time Villa have beaten Chelsea in back-to-back league games in 30 years, while Mauricio Pochettino's side have made their worst start to a top-flight season after the opening six games since 1978/79.
But as has often been the case this season, Chelsea had their chances to score, with Emiliano Martinez making a string of fine saves, but were once again unable to find the net. They have now failed to score in their last three Premier League matches.
Aston Villa too had a raft of chances, but eventually made one count when Watkins (73) fired home on the tightest of angles after a fine break with Moussa Diaby.
It came 15 minutes after Malo Gusto was shown a straight red card. It was initially a yellow after a crunching challenge on Lucas Digne, but upgraded by referee Jarred Gillett after he consulted the pitchside monitor.
