Arsenal fans were furious at manager Unai Emery yesterday evening at his decision not to start Kieran Tierney - as the Gunners slipped to a defeat.

Sheffield United earned a 1-0 win over Emery's side at Bramall Lane.

Supporters of the London giants slammed their manager for some perceived dodgy decisions they claim cost them the points - including choosing Sead Kolasinac over £25million man KT.

And some even demanded the board SACK Emery over his personnel choices.

One blasted: "All this build up from Arsenal and they don’t start Tierney. WTF".

Another wrote on social media: "If Tierney is fit enough to be on the bench he should he fit enough to start ffs."

One commented: "No tierney? No bellerin? No ozil? EMERY OUT".

One moaned: "Kola starting after 4 days of training? Why did we even buy Tierney?"

Tierney is yet to feature in the Premier League since his move from Celtic.

He has starred against Nottingham Forest in the Carabao Cup and Standard Liege in the Europa League.
