Despite a frustrating campaign, Newcastle’s internal stance remains clear that they cannot afford to sanction the departure of multiple key players in one window.
The Magpies are already facing the likely exit of Sandro Tonali, who continues to attract strong interest from Champions League sides across England and Europe, while Tino Livramento is firmly on the radar of Manchester City.
There is also ongoing attention surrounding Bruno Guimaraes, although Newcastle’s preference is to tie the midfielder down to a new contract rather than entertain offers.
Against that backdrop, England international Gordon is viewed as integral to the club’s plans.
Newcastle are eager to avoid a scenario where their squad is stripped of its core - and the message internally is that their £80 million-rated attacker is not for sale.
However, that position is expected to come under increasing pressure.
Sources have confirmed to Flashscore that both Arsenal and Bayern Munich are registering genuine interest in Gordon, with at least one of those clubs anticipated to make a concrete move that would test Newcastle’s stance in the summer.
Arsenal see the left side of their attack as an area in need of improvement, and Gabriel Martinelli could leave the club. Meanwhile, Bayern believe the successful transfers of Harry Kane and Michael Olise can be used to show Gordon how he can take his game to another level by leaving the Premier League.
Previous admirers including Liverpool and Chelsea also remain a factor, as there is a feeling both could re-enter the race if he becomes available.
While there has been a long-standing belief that Gordon is settled and not actively seeking a move, the calibre of potential suitors presents a different challenge that could turn his head.
With one competing at the top of the Premier League and another dominating the Bundesliga, Newcastle acknowledge privately that keeping hold of the 25-year-old could become increasingly difficult as the next transfer window develops.
