Arsenal noticed groin weakness in summer signing Saliba
Arsenal have one small concern about summer signing William Saliba, according to reports.
The 18-year-old was instantly loaned back to Saint-Etienne after the two clubs agreed upon a transfer.
The Athletic says the Gunners were concerned about the centre-back's 'groin strength' when he first arrived at London Colney.
Despite those qualms, the club are generally happy with Saliba as a prospect and are looking forward to his return next season.
The two clubs are in constant contact over the 27m signing, who has made three appearances for the Ligue 1 club this season.
