To put it in context, Antonio Valencia was dutifully patrolling one flank, with Ashley Young clanking up and down the other. Alexis Sanchez was still hoping to offer a sight of his previous self. And Arsene Wenger was bidding goodbye to 20 years' worth of visits to Old Trafford.
That is the last time Manchester United ran out winners against Arsenal in the Premier League. April 29, 2018.
Since then, the sides have met a further five times over two years, and United have not tasted victory again.
Manchester United have only beaten Arsenal once in the league in the past two years
Arsenal recorded their first league win at Old Trafford since 2006 in November last year
Three managers have since been and gone - Wenger, Unai Emery and of course, Jose Mourinho.
