The Gunners signed the centre-back from Saint-Etienne in 2019 but he will not arrive until the end of the season having remained in France on loan
William Saliba has all the attributes needed to be a major success at Arsenal, according to Bacary Sagna
Saliba signed for the Gunners last summer from Saint-Etienne in a £27 million ($34m/€30.1m) move, but as part of the deal he agreed to remain with the Ligue 1 side on loan this season.
He is due to link up with Arsenal at the end of the current campaign and when he does arrive, Sagna - who had a seven year spell in north London and made 284 appearances - believes he has what it takes to go on to be a big hit.
