In-form Luis Suarez, who himself left Anfield for the Nou Camp during the summer of 2014, added a second before the break and Paulinho tapped in a late third as the Blaugrana consolidated first place ahead of Atletico Madrid.
Despite yet another victory for Barcelona, their 15th from 18 games in La Liga this season, the focus of the day was very much on record-signing Philippe Coutinho, who watched his new side from the stands.
I know we're all probably sick of this entire saga, but the official unveiling is tomorrow and Phil Coutinho has just given his post-transfer interviews.
Coutinho nonetheless thanked Barcelona fans for their warm welcome as he was presented on the pitch at Camp Nou on Monday.
'It's a kind gesture. We are in touch all the time and I look forward to seeing the property with my family. It's a dream come true!
"I think he can bring a lot to the team".
Levante coach Juan Muniz had challenge his players to neutralise the threat of Lionel Messi to give themselves hope of a positive trip to the Nou Camp, but like so many before, it proved Mission: Impossible.
The entire piece is well worth a read, revealing a player who can't hide his excitement about living his dream and signing for the biggest club in the world.
However, it had always been widely expected, in both England and Spain, that the Blaugrana would return for Liverpool's star man upon the opening of the winter transfer market this past Monday, with Barca having finally pushed a move for Coutinho over the line with an offer totalling around £140 million (including bonuses) on Saturday night.
"It is true that I have seen videos of him playing in different positions, for Liverpool and for his country".
