Arsenal fans were left fuming after Kieran Tierney was left out of the Arsenal starting XI to play Sheffield United on Monday evening.The summer signing from Celtic has yet to make his Premier League debut following his £25m move to The Emirates.He has, however, played in both the Europa League and the Carabao Cup – against Standard Liege and Nottingham Forest respectively – though Unai Emery opted against utilising him in the clash with Chris Wilder’s men at Bramall Lane.Sead Kolasinac played at left-back instead and fans were disappointed as the Gunners slipped to a disappointing 1-0 defeat, wasting the chance to move third in the table in the process.
Lys Mousset’s solitary goal proved decisive following Nicolas Pepe’s horror miss in the first half.
And supporters were quick to take to Twitter to slam Emery for his team selection.
