Arsenal recruit faces six weeks on the sidelines with groin injury

Arsenal has confirmed that new signing Kieran Tierney will miss Sunday’s opening fixture against Newcastle due to a groin injury.

The Scottish left-back joined the Gunners from Celtic for £25m on Deadline Day but his new side says he will not be able to take part in full training for between four and six weeks.

Mesut Ozil and Sead Kolasinac are also out over security issues

Tierney struggled with injury towards the end of last season and featured just three times for the Hoops in their final nine matches of last season.
