The sporting director revealed his club's happiness following their 'successful' transfer campaign which has seen a host of star players arrive in the French capital
Les Parisiens splashed the cash to sign some of football's biggest stars, including AC Milan's Zlatan Ibrahimovic and Thiago Silva, Napoli's Ezequiel Lavezzi and Sao Paulo's Lucas Moura.
And earlier this month they completed their summer spree with the capture of highly rated Dutch defender Gregory van der Wiel and Leonardo is happy with the club's recruiting.
"Honestly, in this transfer window we did everything we aimed to do," he told RMC.
"I'm not talking only of getting the five players we wanted, but also their qualities, how they will fit into the team and their individual profiles.
"It was a successful transfer window. We took to it studiously and we got the players we wanted."
Having departed with over €150 million [£121m] to build their star-studded squad in addition to offering highly generous salaries, it remains to be seen how France president, Francois Hollande, and his proposal for a 75 per cent tax to be imposed on those earning over €1m [£800,000] per year will affect PSG and French football clubs, in general.
As reported by Goal.com up to 150 players may be affected by this new tax law, should it be imposed.
Head of the Union of Professional Football Clubs, Jean-Pierre Louvel, fears the possible effects the new tax policy could have on French football.
"We fear that it might lead to an exodus of players. We pointed this out to the Minister of Sports (Valérie Fourneyron). Currently, only PSG could now be able to take on this tax. For other clubs, there is no question that they cannot pay," he told RMC.
"Unless the clubs cover the tax themselves, which only PSG are in a position to do, players who have to pay it themselves may leave. We have provided the possible consequences of this new tax to the Minister for we believe were this to happen it would also have a negative affect on the economy, in general."
