Newcastle United are reported to be closing in on their second deal of the summer - withl Ismaïla Sarr the latest player to be linked with a St James's Park switch.
The Senegal international, according to France Football and L'Equipe, has been subject to a £10.4million bid from the Magpies.
But Metz, where the 19-year-old plies his trade, are rumoured to be wanting closer to £13million this summer.
It is known that Benitez is seriously looking to strengthen the wide areas of his United XI next season.
The manager already has star man Matt Ritchie at his disposal, as well as securing a deal for Christian Atsu from Chelsea in the days after promotion to the Premier League was secured.
Rolando Aarons, should he prove his fitness after a season out with injury, could also provide first-team competition.
But beyond that options are light with Yoan Gouffran and Sammy Ameobi both set to depart at the end of their respective contracts.
Winger links have not been short in supply this summer. In fact, that goes for every position with the amount of players rumoured to interesting the Magpies edging close to the 100 mark.
Andros Townsend, among many others, has been heavily linked with a return to the club in recent weeks, with Benitez a keen admirer of the England winger's talents.
United failed in an attempt to broker a January deal for Townsend, with Crystal Palace hanging on to the wideman for their top flight relegation battle.
And should that deal prove too difficult to do this summer, with Palace still searching for a new manager and no decision made on Townsend until the new man settles into the Selhurst Park job, Sarr could become a viable, young and relatively cheap option.
Sarr played 31 times for Metz last season in Ligue 1, scoring five times.
Lille are also credited with an interest in the African prospect.
Last month, Metz coach Philippe Hinschberger said of the player: "He runs at opponents, he's quick and he's someone you don't like to defend against, so we like to have him."
