Klopp felt it was the Scot's best performance of the season.
“He has not had to wait, he has had to train and to learn," Klopp said. “That is a different thing.
“Only because everybody is asking, it looks like he has to wait.
“He made a big step today. His first two games were good, but Robbo can do much better and he knows that.
"He has to gain rhythm, get more confident and today was a game where he really made a difference.
“The first pass he played from the back for, I think, Roberto? He couldn't get it, but that was the idea we worked on. The first goal I think is 40 per cent him, because without his run at the back of Phil things would be different, no?
“He did really well and we are happy for him."
