Mikel Arteta insists Arsenal defender William Saliba can get even better - despite already being one of the best centre-backs in world football.

The colossal Frenchman, who has marshalled the Premier League leaders to back-to-back clean sheets, is striving to oversee a second shutout of Manchester United this season having also scored in this very fixture last term.

When asked if there is even more to come from Saliba, defiant boss Arteta replied: "So much! In every area I look at him, there is growth and potential there and he really wants it. I think he will go to different levels in the next few years."

Arteta has challenged the 24-year-old to not only sharpen his defensive tools - but also mirror Gabriel Magalhaes ' goalscoring exploits, too.

Since the start of the 2022-23 campaign, when Saliba first partnered the Brazilian at the heart of Arsenal's defence, Gabriel has mustered an impressive 16 goals at club level.
