Newcastle's interest in signing a goalkeeper has made Martin Dubravka's position at St James' Park uncertain, according to Sky Sports reporter Keith Downie.

The 29-cap Slovakia international has been the Toon Army's number one for the last four seasons but faces an anxious wait heading into the summer transfer window.

What's the latest news involving Dubravka?

Since coming into the side in November, Dubravka has been a mainstay under Eddie Howe, playing every minute in the last 22 top-flight games.

During that period, Newcastle have improved significantly, rising from bottom of the table to ninth in the Premier League, with the goalkeeper keeping a notable seven clean sheets, one of which came in the victory over Norwich on Saturday.

However, with Newcastle set to sign a goalkeeper when the window reopens for business, the 33-year-old could slip down the pecking order next season.

What did Downie say about Newcastle?

He told GIVEMESPORT: "It's interesting, because it kind of begs the question, does Eddie Howe see Dubravka as his number one moving forward?

"He's obviously played every game and he's a very good goalkeeper, but the fact there was interest in [Dean] Henderson in January and the name of [Bernd] Leno has been mooted around makes you think, they have been looking at the goalkeeping situation, although whether that's as a number one or number two, I'm unsure."

Which goalkeepers have Newcastle been linked with?

Henderson was on Newcastle's radar in January, although Manchester United weren't willing to let him leave despite being one of three senior goalkeepers at the club, along with David De Gea and Tom Heaton.

However, the Magpies could revisit their interest in the ex-Sheffield United loanee this summer, with Henderson on a four-man shortlist of potential new shotstoppers, according to the Daily Mail.

Henderson is joined by two other Premier League-based keepers in Leno and Kepa Arrizabalaga, who are out of favour at Arsenal and Chelsea respectively, with Sam Johnstone completing the list.

However, Newcastle face stiff competition for free agent Johnstone, with the likes of Tottenham and Manchester United also in the race for his signature.

Regardless, if Newcastle do add to their goalkeeping department, it could be bad news for Dubravka, especially with the Slovak turning 34 in January.
