The goalkeeper is likely to be out-of-favour at St. James' Park next season and has been linked with clubs including Everton and Crystal Palace.
There already appears to be a queue forming for the services of forgotten Newcastle United goalkeeper Tim Krul, and the Daily Star claims that the Magpies' north-east rivals Middlesbrough are the latest club to join the hunt.
Krul began last season as Newcastle's first-choice stopper but a ligament injury suffered in October scuppered his chances of holding onto that position for the rest of the campaign.
In his absence, first back-up man Rob Elliot impressed in the limelight, and then once the Irish international also picked up an injury young third-choice Karl Darlow took his chance with both hands.
Now, with it being reported that Newcastle are on the verge of completing the signing of Gent number one Matz Sels, it would seem that Krul's position at St. James' Park is very precarious indeed.
The Dutchman has already been linked with moves to Premier League sides Everton and Crystal Palace, as well as a report suggesting that AC Milan could make a surprise bid to bring him to the San Siro.
According to the Daily Star, Middlesbrough, who are thought to have been beaten by their rivals to the signing of Sels, are the latest club to turn their attentions to the Netherlands international.
The paper claims that Boro have been monitoring Krul's situation for almost a year, and now believe the time is right to make their move following his fall from favour and their promotion back to the top flight.
The Teeside club relied on the impressive form of 37-year-old Dimitrios Konstantopoulos last season, but they are likely to want a younger alternative with Premier League experience to bolster their survival bid.
Krul has just a year left on his contract and with the Magpies now seemingly inundated with options between the posts, the 28-year-old could well be available for a bargain price.
