Not too many Liverpool fans would have heard of young goalkeeper Shamal George before the club's pre-season clash against Huddersfield Town at the John Smith's Stadium this evening.
George, 18, is a promising young 'keeper and one day may well go on to become the club's No.1.
For now, though, he is still very much learning the trade but would have been boosted by his inclusion in Klopp's squad ahead of their latest friendly.

Ultimately, though, with just over 25 minutes remaining, George was the only player that hadn't been utilised by his manager.
And then it happened...Brazil midfielder Lucas, who had only just entered the field of play from the bench, pulled up with an injury and had to be replaced.
Klopp had no choice but to hand George his debut...up front. It's fair to say that it's an introduction the youngster will never forget.
With 25 minutes remaining, how did George get on? Well, he came close to assisting a goal for the Reds, but even more impressively, almost found the back of the net.
Indeed, he found himself one-on-one with the Huddersfield shot-stopper but the linesman flagged him offside. So close yet so far away.
As you can imagine, then, Liverpool fans reacted hilariously as George replaced Lucas.
Here are the best tweets:
George may not have been able to find the back of the net, but that didn't stop Klopp's side securing yet another pre-season win.
New signing Marko Grujic opened the scoring with a well-taken half-volley, while Brazil midfielder Philippe Coutinho failed to double the lead from the penalty spot.
Liverpool were handed a second penalty in the last couple of minutes and defender Alberto Moreno didn't disappoint as the club claimed a 2-0 victory.
