'We’ve been abandoned!' - Oliver Glasner criticises Crystal Palace board in extraordinary rant about transfer strategy after Sunderland defeat

Further player movement is anticipated, as striker Jean-Philippe Mateta is also open to a new challenge, with Juventus holding talks with his representatives for a potential transfer. Having already sold Eberechi Eze to Arsenal last summer, the club faces a challenging period of transition and a potential exodus of its best talent, leaving a significant rebuilding job for the next manager. And Glasner has revealed the levels of frustration with the club are at boiling point.

After the match, Glasner told the BBC: "I feel we are being abandoned completely. I can't blame any player. They did everything they could and this has been going on for weeks and months now. We have 12, 13 players from the squad available and we feel no support. The worst thing is selling our captain one day before playing a Premier League game.

"We are preparing, it's the first (full) week we are training since September, and then we are selling our captain one day before a game. So I have no understanding of this. I have always kept my mouth (shut), but I can't because I have to defend these players, because it was the 35th game today. Yes we get under pressure here and we are unlucky. But again, you can't react, we can't help them, it makes it really tough."

Glasner bemoans timing of departures

The Palace boss continued: "If you get your heart torn out twice this season, one day before a game, it was with Eze in the summer, it was with Guehi now. What should I tell the players all the time? What should I tell them? And then I see the performance today for 50, 60 minutes - it was not easy with all the circumstances going here with 12 players from the squad. I look at the bench, I can't react, just kids on the bench, and this has not happened yesterday, this is weeks ago. That's why I'm really frustrated today."

When asked if he wanted to leave sooner than the end of the season, he added: "No, never, I would never. I will go with this group of players until the end. I have so much respect for their character. I see they're disappointed and I know how hard they are working, I see how hard they are fighting at the end. Never, no chance. I have said to the players we have to stick together, if we don't get the support it's us that have to do it. There is nobody else, we are the only ones, we are the ones who have to play."

Glasner will be left to make plans without his captain and, potentially, also lose talismanic striker Mateta in the coming weeks. And there’s the small matter of the London derby with Chelsea looming on the horizon, with no guarantee Glasner will be in the dugout at Stamford Bridge for the clash.
