William Saliba will be a 'fantastic' addition for Arsenal, according to his Saint-Etienne manager Claude Puel.
The 19-year-old joined the Gunners in a £27million summer deal from the ASSE last year, before being loaned back to Ligue 1 club.
But with Arsenal yet activate the option to extend David Luiz's contract by 12 months, Saliba could be brought into as early as June, when the Premier League return.
Saliba, who has been tipped for a bright future, needed more regular game time at the top level before slotting straight into the heart of Arsenal's defence.
