Gabriel scored the winner to return Arsenal to the top of the Premier League in a hard-fought 1-0 win over Chelsea at Stamford Bridge.
Manager Mikel Arteta remains unbeaten in all of Arsenal’s Premier League visits to Stamford Bridge since he took the reins in December 2019, as his side left with all three points.
The central defender poked a probing goalward-bound looped effort from Bukayo Saka over the line for the only goal of the game in the 63rd minute.
Chelsea had been looking to return to winning ways in the league having been hammered 4-1 at Brighton the previous weekend, with manager Graham Potter suffering his first defeat since he took charge of the club in September.
However, the Blues struggled to impose themselves on the game, and finished with only two shots on target.
Meanwhile, Unai Emery enjoyed a dream start to life in the Aston Villa hotseat as meek Manchester United fell to their first Premier League loss at Villa Park since 1995.
A run of 23 winless home league games against the Red Devils stretching 9,941 days came to an end on Sunday as Steven Gerrard’s successor oversaw a 3-1 victory in his first match in charge.
Leon Bailey struck and Lucas Digne scored a delightful free-kick within the opening 11 minutes at a rocking Villa Park, where Jacob Ramsey atoned for deflecting in a Luke Shaw strike by scoring a fine effort just after half-time for Emery’s elated side.
The result ends United’s nine-game unbeaten run in all competitions and sets up an interesting reunion in the Carabao Cup on Thursday.
