A section of Arsenal fans have expressed their disappointment after manager Mikel Arteta confirmed that Kieran Tierney could be out injured for the rest of the season.

The left-back sustained a knee ligament injury during the 3-0 league defeat to Liverpool earlier this month. It was initially confirmed that he would be sidelined for a minimum of four weeks.

“Kieran is out, probably for the season,” he told Arsenal.com.

The news has been received with plenty of disappointment from some of the club’s supporters, and here are a few reactions on Twitter.

Knew it, gutted .
