Ex-Celtic defender Kieran Tierney has had his fitness questioned by Liverpool legend Jamie Carragher.

The Arsenal left-back has had various injury problems since making his move to the Emirates in 2019.

This included a double hernia problem which he underwent surgery on not long after signing for the Gunners. 

There was also a knee injury sustained on international duty with Scotland in March, which caused him to miss the rest of the season, including the World cup playoff defeat to Ukraine.

The 25-year-old now has some stern competition for the first-choice left-back role in Mikel Arteta's side, with the club signing Olexander Zinchenko from Manchester City.

While the Ukrainian can also play in midfield, he was preferred to Tierney during the opening game victory against Palace.

Now Carragher has spoken about how a new left-back was essential after the Scottish international has struggled to maintain his fitness so far in his three seasons at the club.

"Arsenal needed to strengthen at left-back because Tierney’s injuries now are becoming a problem for him and for the team," he told Sky Sports.

The 25-year-old has become a firm fans favourite at the Emirates, with many Gunners supporters shouting for him to become club captain last season after the departure of Pierre Emerick Aubameyang in January.

With the signing of Zinchenko, though, it is now going to be essential that the former Hoops player stays fit to try and fight for his place in the team.
