Liverpool boss Jurgen Klopp blamed the FA Cup ball for last night's defeat at Chelsea.

Willian's effort from the edge of the area slipped from Adrian's grasp after only 13 minutes of their FA Cup encounter at Stamford Bridge on Tuesday night.

But Liverpool manager Klopp was in no mood for blaming his players after a slack passage of play.

"The first goal, we lose a ball, what was it 18, 19 yards in front of the goal?" Klopp said.

"The specific characteristic of the ball and Willian's shooting technique made life really difficult.

"Before that Adrian saved a sensational ball. He caught the ball and quick restart, which was a good idea, but not everybody was ready.

"Fabinho was surprised by the pass. We wanted to play like this but we lose that ball and they finish it off."
