The 17-year-old struck just before half-time to catch up with the Premier League champions in the FA Cup third round at Villa Park, after Sadio Mane threatened to open the floodgates with an early header.
A strong Liverpool side eventually took the game away from the youngsters in the second half, with Gini Wijnaldum, Mane and Mohamed Salah all scoring five minutes apart to make it 4-1.
But with the Villa youngsters put into action following the positive cases of coronavirus in the first team, Klopp knew all post-match talk would rightly be about his opponents.
“The boys did really well. Little Jamie Vardy was a real threat, ”the Reds boss told talkSPORT.
In a separate interview on BT Sport, he added, “The kids did really well, that’s good.
“We had football problems. We needed a little more time, but it was quite clear.
“Passing and movement problems. Too many players on the wrong side of the ball – not enough pass recoveries. We had chances and shot the ball straight at the goalkeeper – we changed it in the second half.
“It was rusty but better in the second half. Against Southampton [1-0 defeat] from the first second, they were no longer on the ground but that was not the case today. ”
Klopp has repeatedly expressed his admiration for Leicester legend Vardy throughout his time in England and often cites the former Englishman as one of Liverpool’s most dangerous opponents.
