Crystal Palace boss Frank de Boer has hit out at Liverpool midfielder Marko Grujic after his bad tackle on Wilfried Zaha.

The Serb was booked after hacking down Zaha in the second-half - and it wasn't the first time he has upset the Eagles.

Palace defender James Tomkins blasted Grujic for a “disgusting” tackle on his ankle in April, which nearly ended his season.

And now, it was De Boer who took a swipe at the 21-year-old following his team’s 2-0 Premier League Asia Trophy defeat to the Reds.

He said: “It was not a nice challenge. I think it was not appropriate because it could injure one of our most important players.

“He [Zaha] is creative and he played a fantastic first-half, so you don’t want to lose these kind of players. I’m happy he’s okay.”
