William Saliba has achieved almost everything a defender could dream of at Arsenal.
The Frenchman is a Premier League champion, a Champions League finalist and is widely regarded as one of the best centre-backs anywhere in world football.
At just 25 years old, he already looks destined to go down as one of the finest defenders Arsenal have ever had.
However, Sol Campbell believes there is still one area of his game that can improve.
What’s your message to John Terry after he said William Saliba is not world-class?
Sol Campbell says William Saliba needs to score more goals for Arsenal
When people discuss William Saliba’s strengths, the list is almost endless.
The Frenchman is quick, composed, dominant in duels and incredibly comfortable on the ball. Very few forwards have managed to get the better of him over the last few seasons.
That is why it is so difficult to find flaws in his game. Even Arsenal supporters would struggle to identify many weaknesses.
Campbell, however, believes Saliba can still offer more in one particular area.

The former Arsenal defender feels the Frenchman should become more aggressive when attacking set-pieces.
Given the Gunners’ quality from corners and free-kicks, there is no reason why Saliba should not be adding more goals to his game.
Campbell told The Athletic: “In the opposition box, Saliba could be more aggressive, gamble more.
“If he can have more positivity in the box to say, ‘I’m going to get my head on this, and stick it away’, he’ll score. That’s the only thing he lacks – a few more goals.”

Sol Campbell has challenged William Saliba and Gabriel Magalhaes to reach another level
Campbell’s advice was not just aimed at Saliba individually.
The Arsenal legend also spoke about the partnership between the France international and Gabriel Magalhaes, which has become one of the strongest defensive pairings in Europe.
However, he believes the next stage of their development is proving they can maintain the same standards even when one of them is missing.

Campbell explained: “Sometimes when one’s not there, it drops off a little bit. That’s the next level they’ve got to get to – you can’t always play with your chosen mate.”
Arsenal’s defence has occasionally looked a little less secure whenever either Saliba or Gabriel has been unavailable.
If those two can learn to elevate the players around them regardless of who is alongside them, they will become even better leaders than they already are.
