The centre-forward Mateta faces an undecided future prospect with negotiations regarding a fresh agreement are said to have stalled.
This French international currently has an existing contract that runs in June 2027, and early conversations during the early months were considered constructive.
But, a conclusion remains to be found, and insiders indicating that the player feels no urgency to pledge his future to Selhurst Park.
Rising Profile and International Aspirations
The striker has solidified himself as one of the most potent strikers in the Premier League, a form that has enabled him earn a place in the France squad.
Since making his international debut in October, he has notched a pair of goals in 3 outings for Didier Deschamps' team.
Furthermore, it is understood that given Mateta now having a genuine chance of being selected for the global tournament squad, his current preference is to consider his alternatives following the competition in the United States and Canada.
Given only a single year remaining on his deal after the World Cup concludes in July, Mateta would be in a very strong negotiating situation if he produces a successful tournament.
Amid the impasse, dialogue involving Mateta and the club is said to be active, with optimism that a new deal could still be signed.
European Interest and Wider Team Situation
A number of continental sides have expressed curiosity in Mateta in recent weeks, notably Italian club Atalanta.
This uncertainty regarding his prospects comes to light at a time when head coach the Austrian's disappointment with the team's transfer business has resurfaced once more.
The coach, who led Palace to their maiden significant trophy by lifting the FA Cup trophy in May, has been balancing the team's league season with their first venture into continental competition.
"We missed a few of opportunities in July and August, to make it easier for us but once more we will remain united and make it better," he commented following Sunday's 2-1 defeat to United.
Glasner continued during his after-match press briefing: "When you play continental competition for the first time in your history, you ought to spend and not save."
"I think January is not ideal [to sign players]. We will have completed over 50% of our fixtures," he said.
"The situation was quite clear and I held my peace anything but now I believe it is equally appropriate to mention it that we let slip the opportunity to have an more successful season in the summer."
Adding to the team's instability, the manager's personal situation is also in doubt. His present deal runs out at the end of the season and there exists no new deal finalized to renew it.
