Sources told AFP the 19-year-old centre-back, who has yet to feature for the Gunners' first team since joining from Saint-Etienne in June, will sign a loan deal on the Mediterranean coast.
"Value doesn't count the number of years," Ursea told a press conference about the youngster by quoting French philosopher Pierre Corneille.
"But nothing is finalised, yet," he added.
The Premier League outfit paid 30 million euros ($36.8 million) in July 2019 for Saliba before sending the France under-20 international back to Saint-Etienne on-loan for a season.
Saliba would come in as cover for injured captain Dante with Ursea's side's first match since the winter break Wednesday's trip to Brest.
