Arsenal boss Mikel Arteta insisted the Gunners have taken the handbrake off after their rout of West Brom.
Alexandre Lacazette's second-half brace and fine strikes from Kieran Tierney and Bukayo Saka earned a dominant 4-0 win at the Hawthorns.
The Gunners have now won three straight games in the Premier League for just the second time under Arteta.


They rose to 11th, three points behind the top six, just weeks after their season threatened to collapse and Arteta was being questioned - but the boss can see progress.
