Arsenal may have made a positive start to the season, but they will face their first true test against Liverpool on Saturday.

A lot of the Reds' success last season as they finished as Premier League runners-up relied on their scintillating front three of Mohamed Salah, Roberto Firmino and Sadio Mane, and the trio are in line to start against Unai Emery's side this weekend.

With such quality in attack, Arsenal will need to be at the top of their game defensively if they are to get anything out of the fixture, and some of the club's supporters have suggested that the best way to go about that is with three centre-backs.

That's certainly not out of the question. Arsenal do have three centre-backs available - David Luiz, Sokratis and Calum Chambers - and Unai Emery used such setups at times last season, including against Chelsea in the Europa League final, although this season he's only used 4-2-3-1.

Gunners supporters have taken to Twitter to share their thoughts. You can see some of the best comments below.
