Paris: Goalkeepers Keylor Navas and Sergio Rico practised saves with tennis balls on Tuesday on the eve of Paris Saint-Germain debut in Champions League at home against Real Madrid.
PSG and Real are in Group A alongside Club Bruges and Galatasaray.
In last season's edition of the Champions League, both teams were knocked out in the round of 16.
The French side was eliminated by Manchester United, while the Spanish giants were defeated by Ajax.
Navas has been a Real Madrid player from 2014 to this summer, when he moved to the French capital.
