The Uruguay international has played only four matches since his £22.8m transfer from Ajax at the end of January, but already he has shown he could prove to be an incredibly shrewd purchase.
His Reds career got off to the perfect start when he came off the bench for his debut against Stoke City and scored within 15 minutes of taking the field.
However, he went up a notch against Manchester United on Sunday when, although Dirk Kuyt's hat-trick grabbed the headlines, the 24-year-old was the star performer with a hand in all three goals.
His contribution for the first, skipping past Rafael, Michael Carrick and Wes Brown before rolling the ball through goalkeeper Edwin van der Sar's legs for Kuyt to tap home had the mark of genius.

And Lucas believes the impact Suarez has already had, with the promise of better to come in the future, has helped erase the memory of Fernando Torres' departure to Chelsea for £50m - funds which were used to bring in the Uruguayan and club-record signing Andy Carroll.
"I don't think Liverpool would pay 25million euros for a bad footballer," joked the Brazil international, who enhanced his growing reputation with another composed display in central midfield against United.
"He has already settled and looks like he has been here for a long time.
"He is really happy and we have helped him to settle, especially outside of the training ground.
"You have to give him the confidence to show what he can do and he has already shown what he is capable of doing.
"We are happy because when you lose a striker like Fernando you expect to have another one.
"He is a fighter, he has a lot of quality, is very strong and quick and can change the game.
"What he did against United was good, especially the first goal, where he did a great job."
