Liverpool boss Jurgen Klopp was delighted with his side in the 2-0 Europa League win over Manchester United but has urged caution.
Only the heroics of goalkeeper David de Gea prevented a landslide at Anfield, although he was beaten by a first-half Daniel Sturridge penalty and a late close-range strike from Roberto Firmino.
Despite taking a considerable advantage to Old Trafford next week, Klopp refused to get too carried away.
“It was good, from the first second to last second with only a few minutes in the second half when we lost control,” he told reporters.
“2-0 is a perfect result. We would have liked to have won more clearly but there is nothing to criticise.
“As a human being I could really celebrate and say it is the best and greatest ever but I don’t want to set a limit for them, I don’t know how strong they can be.
“We are in a good position now and want to go to the next round but for this we have to play like this again.”
Klopp was impressed with the Anfield atmosphere, and added: “It was unbelievable. I want to say thank you to everyone who was involved it was easy to enjoy from the first to last second.
“That was Liverpool as I knew it before I came here. It was really great.”
