Arsenal fans have been left raging at manager Unai Emery after former Celtic star Kieran Tierney was named on the bench for their tie against Sheffield United.
Gunners supporters were excited to see the £25million summer signing in action for the first time in the EPL tonight from the start.
Tierney has played twice already for the North London outfit, having made two appearances so far in the Carabao Cup and Europa League .
The former Celtic left-back has taken a while to get back to full fitness after recovering from a double hernia operation that he had at the end of last season.
He was expected to feature from the get go, but Sead Kolasinac remains as left-back for Arsenal tonight.
And supporters took to social media to slam the Gunners boss.
