Alexander-Arnold was a topic of discussion in the post-match analysis, with both Jamie Carragher and Graeme Souness focusing on his role in the opener.
When this was put to Klopp, he was quick to defend the 19-year-old.
“Who were the pundits?" asked Klopp. “Rashford is coming at 100mph in that situation, Trent makes this move, he cuts back and then there needed to be another player.
“Could Trent have done better? Probably. But could he have solved the situation alone? There needs to be a second player.
“Pundits are former defenders and unfortunately they made similar things, in similar situations. It was a brilliant goal from Rashford.
“One of them (Carragher) was for sure, a full back from time to time when he was young."
