The youngster was handed his first start in a Reds shirt on Thursday evening and was arguably their best player on the evening in a dull 0-0 draw.
He proved a danger throughout the game, with him providing an attacking edge from the left back spot with a number of dangerous runs and crosses.
His performance did not go unnoticed by Jenas, who praised his display and said it was a big positive for Klopp that he could call upon the youngster.
“He delivered, and it was a tough game to deliver in,” he told BT Sport.
“He offered so much down that left side, the majority of their good play came through him.”
“That’s a real positive for Jurgen Klopp that a young lad can come into the time and show good character and quality. He looks to me like someone Jurgen Klopp can call on.”
While Smith was impressive in the Europa League, it is unlikely he will be handed much more first team football for a while.
The left back position had been something of a weak spot in the side under Brendan Rodgers, with several signings failing to impress.
However, Alberto Moreno has started to improve under Klopp’s guidance and has made the position his own in recent weeks.
So, despite Smith’s strong showing on Thursday, he still faces a fight to start in the position in the future.
