Hertha Berlin midfielder Marko Grujic has warned parent club Liverpool not to underestimate Cardiff City today.

Grujic spent a portion of last season on loan in South Wales, helping the Bluebirds gain promotion to the Premier League.

"Liverpool will know what is to come," Grujic told Goal. “It will be a direct style, some long balls and then pressing to try and attack the second ball in the opponents' half. They rarely change.

“Some people criticise Neil Warnock because of the way his teams play. He's seen as someone who plays only long-ball football or a direct style, but he always has a clear plan. And most of the time, it works.

“It's about security. He doesn't want to lose many balls in the middle, he wants to play long and then to press high and win the ball closer to the goal. That's what Cardiff will do on Sunday."
