The 27-year-old scored both goals in Paris Saint-Germain's 2-0 Champions League win over Dynamo Kiev on Wednesday night and the club's sporting director was quick to heap praise on him.
"It was not an easy game but Lavezzi was extraordinary. His first goal changed the game and his second wrapped it up," he told RMC.
The result ensures the club qualify for the knockout phase of the competition for the first time in nearly two decades and Leonardo highlighted the importance of the achievement.
"Qualifying for the knockout stage very important to us, this is the first time in 17 years it has happened," he added.
"We are now competing against Porto for first place and will strive to win the group. We now know we will be in the competition until March at least, which means that our aim is just to focus on Ligue 1.
"Everything is very exciting around the club, we are new and learning all the time. There are many things that are not perfect but the qualification will accelerate the process of becoming the best."
