Jurgen Klopp has blasted the pitch at the Cardiff City Stadium - claiming it put his Liverpool players in danger.
The Reds ran out 2-0 winners in South Wales to return to the top of the Premier League thanks to goals from Gini Wijnaldum and James Milner.
But Klopp was unhappy with the playing surface and revealed after the game the grass at Melwood had been left dry in preparation for the match.
The win takes Liverpool to 88 points, their highest ever Premier League haul, with three games left to play
They are two points clear of Manchester City , who play their game in hand at Old Trafford on Wednesday night.

“Dry pitches are dangerous for players injury-wise. If you run and stop in a moment it [injury] can happen. You know why people leave a pitch dry — I don’t have to say that," Klopp said.
“The ball doesn’t roll that quick. If you ask footballers what do you want they will say a wet pitch, you can slide better, everything.
“I spoke about it at West Brom and was told I was a sore loser. This time we were prepared. We learned from our mistakes in the past.
“It doesn’t make football easy when the pitch is that dry, it is dangerous as well. You have to stay patient and calm, you have to stay 100 per cent on set pieces.
“We trained on a bone dry pitch to get used to it.”
