Saint-Etienne head coach Claude Puel has questioned the logic behind Arsenal's signing of William Saliba after the Frenchman was left out of the Gunners' 25-man Europa League squad.
The highly-rated defender signed for the north London club last summer for a £27million fee but was immediately loaned to the Ligue 1 club for the duration of the 2019-20 season to continue his development.
The 19-year-old's surprise omission after finally arriving at the Emirates this summer and a failed second loan move back to his former club before the overseas deadline means he is likely to struggle for game time this season.
