Nacho Monreal and Alex Iwobi stretched Arsenal’s winning run to four consecutive games in all competitions as Alexis Sanchez dazzled in the 2-0 Premier League victory over Brighton and Hove Albion.
Monreal’s opening goal arrived after Alexandre Lacazette was denied by the post during the early stages for Arsene Wenger’s side, although Solly March was similarly close to a Brighton equaliser before half-time.
Sanchez took centre stage after the break and set up Iwobi to double the Gunners’ advantage with a sublime backheel.
The 28-year-old forward was unable was unable to claim a maiden Premier League goal of the season but his performance offered a vindication of Wenger’s hardball transfer window tactics, which left Sanchez unable to complete a deadline-day move to Manchester City.
Arsenal are unbeaten in seven matches since their 4-0 humbling at Liverpool in August and are now level on points with defending champions Chelsea in fourth.
Lacazette unleashed a rasping 25-yard drive against the post inside two minutes and Arsenal dominated the opening exchanges with pleasingly slick interplay.
Clear-cut chances were not forthcoming, however, and it took a more robust approach to bring about the 16th-minute opener.
