Liverpool manager Jurgen Klopp had positive words for youngster Bobby Clark last night.

The Reds were rampant against Sparta Prague in the Europa League round of 16 second leg.

5-1 up from the first leg, Liverpool won the second leg 6-1 to emerge into the quarter finals.

Post-game, Klopp said on Clark getting his first goal: “Bobby, it's really nice to see the boys develop and flourish, to be honest. That was a top performance of Bobby.

“A real performance. Goal yes. But he set up whichever goal with winning the ball back up high, really high pressing situation – top, top, top. And then controlling a football game, with all the excitement inside that he definitely still has, is fantastic.

“He is the only one we worry a little bit [about injury-wise]; I hope it's nothing but he sat there and said he felt something, so we had to take him off. Besides that, everybody else should be fine.
