It was a horror show for Arsenal under the Friday night lights as they crashed out of the FA Cup at home to Manchester United at the Emirates Stadium.
Unai Emery's Gunners faced a tricky fourth-round clash against Ole Gunnar Solksjaer's United, with the Red Devils' caretaker manager winning his first seven games in charge at Old Trafford.
And Alexis Sanchez scored on his return to the Emirates as United saw off Arsenal to reach the fifth round. The two most successful sides in the competition's history played out an entertaining Friday night game as United secured a 3-1 win an an eighth straight victory for interim manger Solskjaer.
Sanchez and Jesse Lingard had set the visitors on course for victory before Pierre-Emerick Aubameyang pulled a goal back for the Gunners, only for substitute Anthony Martial to wrap up a comfortable win with a late strike.
The match may also have lasting consequences for the Gunners, with Laurent Koscielny and Sokratis going off injured to add to Emery's defensive woes during a transfer window in which he is restricted to loan signings.
