William Saliba has the potential to be Arsenal's version of Virgil van Dijk, according to Alan Smith, who thinks Mikel Arteta can turn the £27 million ($35m) star into a "classy defender".
Arsenal reached an agreement to sign Saliba from Saint Etienne last summer, before sending him back to Geoffroy Stadium on loan for the duration of the 2019-20 campaign.
The 19-year-old featured in 17 games for the French outfit before Ligue 1 was cancelled in April due to the coronavirus outbreak, helping Claude Puel's men narrowly avoid relegation despite dealing with persistent injury issues.
