The Uruguayan scored four goals in the Reds' 5-1 victory over the Canaries at Anfield in the Premier League on Wednesday.
"The headlines are simple - that was just sheer brilliance," he told reporters. "It was a joy for me to watch the team tonight, tactically we were very good. It was a remarkable individual performance. I always like to talk about the team but you've got to hold Luis up tonight as one of the best strikers in the world. It was an incredible performance.
"If you put him out on the pitch, you know you're going to get determination and the will and the desire to succeed, which is important, but the quality of his finishing is just at a really high level - and none more so than tonight. The repertoire he showed was incredible really. I felt for the Norwich defenders, because if you come up against someone like that who is a top, world-class payer, it's very difficult to contain him.
"I think if you look at Lionel Messi and Cristiano Ronaldo - those two have been out on their own for a few years. But Luis is still only 26 and I really think he's going to make improvements to his game over the coming years. We do a lot of work and we talk about the improvements in his game and how he can improve."
Liverpool are currently fourth in the league table.
