Newcastle United have rejected a bid for Karl Darlow.
The Sun report that Middlesbrough had a £5million offer for the goalkeeper turned down.
Darlow helped Newcastle win the Championship title last season.
And Darlow must choose between staying and fighting for his place – or guaranteed first-team football elsewhere.
Reading are also interested in the 26-year-old, who joined United from Nottingham Forest in 2014.
Middlesbrough are expected to return with an improved bid for Darlow, who was outstanding in the club's Championship-winning season.
Reading could also table an offer.
Benitez has already loaned goalkeeper Matz Sels to Anderlecht.
