PARIS, Feb 3 (Reuters) - Paris St Germain forward Bonaventure Kalou believes Argentine playmaker Marcelo Gallardo will be the team's key player when the Ligue 1 strugglers travel to arch-rivals Olympique Marseille on Sunday.
'His arrival is a good thing for the club. He is kind of player we were missing in the squad,' the Ivory Coast international told OM's website on Saturday.
The former Argentine international, who played in Ligue 1 with Monaco from 1999 to 2003, joined the Paris side from River Plate during the January transfer window.
Paris St Germain, who were humbled 3-1 by Marseille at Parc des Princes earlier this season, are 16th in the standings.
Fourth-placed Marseille, who trail third-placed RC Lens by one point, will have an eye on the top three, four days after beating Olympique Lyon 2-1 in a French Cup last-16 tie.
'We come here to bring something back home but it will be hard,' said Kalou.
'Marseille are one of the most dangerous teams of the moment.'
The match, with 1,100 PSG fans travelling to Provence, will be heavily policed.
'Security measures will be reinforced in and around the Stade Velodrome,' said the police authorities.
Some 500 police officers and 680 stewards will be mobilised for the game due to kick off at 2000 GMT.
