The Black Cats have endured a turbulent off-season, with manager Sam Allardyce, who saved the club from relegation last term, having been poached by the FA to succeed Roy Hodgson as England chief.
The saga surrounding ‘Big Sam’s’ future has somewhat derailed transfer business on the North East, with the only activity to have taken place at the Stadium of Light having centred around those leaving the club.
However, with ex-Manchester United and Everton chief Moyes now in charge, Sunderland appear to be plotting for additions, and reports claim that Salvio is wanted,
The 26-year-old Argentine is rated at €25m (£21.1m) by the Portuguese club after he helped them to secure the Primeira Liga title last term.
Salvio can play on either flank in an attacking midfield role, and with reports last week having suggested that Benfica’s president is actively trying to sell him, it appears that a deal could feasibly be reached.
