Paris Saint-Germain coach Laurent Blanc has urged midfielder Marco Verratti to cut down on his risk-taking in his own half.

PSG go into Friday night's Ligue 1 clash with Valenciennes on the back of a 1-1 draw with Monaco , in which Verratti was criticized after twice conceding possession in dangerous areas.

Blanc admits that aspect of the youngster's game is a cause for concern but sees it as a consequence of Verratti's transition to a deep-lying midfield role.

"He has sometimes taken on a bit too much for my taste," Blanc said.

"He is starting to look after the ball better, but it takes time - he is only 21.

"Before, he played further forward, he maybe forgets that he is now playing further back and that he is often in his own half.

"He should continue to take risks, but in opposition territory. He needs to play more simply and efficiently (in defensive areas)."

PSG will be without injured trio Edinson Cavani, Christophe Jallet and Zoumana Camara for this week's game.

Zlatan Ibrahimovic will play despite a slight back problem while strike partner Ezequiel Lavezzi has trained as normal despite being, by Blanc's admission, "affected" following the murder of his uncle in Argentina.

Valenciennes coach Ariel Jacobs refused to write off his relegation-threatened side's chances against PSG, who lead the standings by five points.

"Paris are the reigning champions and challengers for this season's title," the Belgian told his club's website.

"They have enormous individual qualities and very often, they produce collective performances of a very high level.

"But, like any team, they also have certain aspects you must exploit, even if it is not often evident due to their experience and quality."

Striker Anthony Le Tallec is being eased back into full training with the squad, with Opa Nguette hoping to soon follow suit.

Abdou Camara has also been limited and Arthur Masuaku and Rudy mater are doubts, while Mody Traore and Lindsay Rose remain sidelined.
