Ian Wright believes Arsenal's biggest downfall is the fact they are too reliant on Kieran Tierney.
The Sky Sports pundit claims Arsenal are unable to 'function' without him following their notably lacklustre performance against Crystal Palace.
The 23-year-old missed the Gunners' 0-0 Premier League draw with the Eagles on Thursday, sparking concern over Arsenal's ability to perform without their star man.
Tierney was withdrawn just two hours before the game in north London with a muscle issue.
He is expected to undergo a series of scans on Friday to determine whether he will be available for Arsenal's game against Newcastle United on Monday.
