The Reds scored three goals in the second half to finish the year in eighth place on the Premiership table.
Rodgers believes that his side are definitely looking sharper and are going in the right direction after playing some decent football in December.
In a chat with Sky Sports he said: "It was an outstanding performance against a very good side in the top eight. For us to perform like that was very pleasing.
"A few weeks back we put a lot of work in to find a way to get that creativity back. We've seen in the last few weeks our intensity and pressing which leads to the creation of chances."
Rodgers said the front three of Lallana, Sterling and Coutinho is making up for the lack of an out-and-out striker in the starting XI.
"It's something we've been searching for all season. We went with a similar system at the beginning of the season as we did last season, going diamond at the beginning.
"But we lost some players. We search for that tactical idea to go with. You look at the effort my players put in tonight; pressure, intensity, squeezing, hunting the ball after only having a game a few days ago.
"[Lallana] got his reward for a great performance and work rate. We asked the players to do that," he added.
