A number of European clubs have shown an interest in Mateta in recent months, including Serie A side Atalanta.
Uncertainty over his future has surfaced at a time when Oliver Glasner’s disappointment regarding the club’s transfer activity has come to the fore once more.
Glasner, who led Palace to their first major trophy when they lifted the FA Cup in May, has been juggling the club’s domestic campaign with their first foray into European football.
Speaking to Match of the Day after Sunday’s 2-1 loss to Manchester United, the Austrian said: “We missed a couple of chances in July and August, in the transfer window, to make it easier for us but again we will stick together and make it better.”
Glasner continued in his post-match news conference: “If you play European football for the first time in your history, you should invest and not save.
“I think January is too late [to add]. We will have played more than 50% of our games.
“Everything was pretty clear and I didn’t say anything but today I think it is also time to speak about it that we missed the chance to play an even better season in the summer.”
Glasner’s own future is unclear. The former Eintracht Frankfurt coach’s current deal expires at the end of the season and there is no agreement in place to extend it.
