ESPN FC's Frank Leboeuf, Don Hutchison and Steve Nicol question if Sadio Mane should have been sent off for hitting Kieran Tierney with his elbow and what Arsenal's takeaway should be from the loss. Leboeuf says players have been given red cards for less than what Mane did and points the finger at Willian for Arsenal, saying he "disappeared completely." Nicol believes now is the time for Mikel Arteta to "earn his paycheck" and keep morale up at the club.
