Ronald de Boer has hit out at Crystal Palace following the “ridiculous” sacking of his brother.

Frank de Boer was axed by Eagles chiefs last month after losing his first four league games.

De Boer enjoyed huge success with Ajax, winning four Eredivisie titles during his six-year spell in charge.

But he has been sacked by Inter Milan and Palace in the last year.

And brother Ronald has slammed the Eagles for pulling the plug on the Dutchman’s time at Selhurst Park. He was appointed on a three-year deal in the summer.

Ronald told BeInSPORT: “It hurts, definitely. He’s a winner and he worked so hard at Crystal Palace to get it going. Finally, when he thought there was a light at the end of the tunnel he got sacked so that hurts even more.

“He has to stand up again. He’s still hungry to coach another team but for sure it was a knock down.

“We just started, that’s why it’s so ridiculous [to be sacked] after four games. They played a good game against Burnley.

“You thought they’d begun to understand a little bit the philosophy, the way. It takes time.

“When you put someone in charge like my brother, you have to speak to him before. Have you thought about his ideas? How, after four games, can you not believe in him anymore? That’s strange.

“That’s football nowadays. Too much pressure, too much money, it makes people make strange choices.”
