The Black Cats have been quiet in the transfer market so far this summer, with the managerial merry-go-round at the club having somewhat put the buffers on incoming deals.
But with David Moyes now in Sam Allardyce’s vacated hot seat, plans ahead of the news season are set to gear up and reports claim that a £21.1m offer for Salvio has been tabled.
It’s understood that club officials have held productive talks regarding the Argentine that have been followed by a bid.
The mooted fee matches Benfica’s asking price, which could lead to Salvio becoming the Wearside club’s most expensive signing, surpassing the £13m they paid for Asamoah Gyan.
The 26-year-old is a versatile attacking midfielder, able to play on either flank or in a central berth.
