Mikel Arteta has praised Arsenal's mentality after claiming his players were unhappy despite winning 1-0 at Manchester United on Sunday.
Riccardo Calafiori scored the only goal at Old Trafford after 13 minutes, nodding in from close range after United goalkeeper Altay Bayindir failed to deal with a Declan Rice corner.
Back in September 2020 -- less than a year into Arteta's first season in charge -- Arsenal had won just two of their last 40 away games at the traditional Big Six sides.
By contrast, in the last two seasons, Arsenal are unbeaten in 20 league matches against Liverpool, Chelsea, United, Manchester City and Tottenham -- a record they extended to 21 on Sunday
