Anelka has joined Juventus until the end of the season after turning out for Chinese outfit Shanghai Shenhua.
Juve are top of Serie A and visit Scottish champions Celtic on Tuesday in the first leg of their last 16 tie in the Champions League.
“The initial impressions of Anelka are very good,” said Matra, who scored his fifth goal of the season in Juve's 2-1 win over Chievo Verona.
“There’s no doubting his quality.
“He’s always displayed his value, he’s used to winning and has a great international pedigree.
“That last aspect will be very useful to us, because there aren’t many in our team who can count on such experience on the European stage."
