(CNN)The Champions League is back -- but there were no big winners on the opening night of the knockout round. Paris Saint-Germain was held to a frustrating 1-1 draw by Chelsea in the French capital, while Bayern Munich finished goalless in Ukraine with Shakhtar Donetsk. PSG will be the most annoyed -- Laurent Blanc's side had chance after chance to win the tie and put a dent in Chelsea's Champions League hopes. In the end, Edinson Cavani's strike ensured parity after Branislav Ivanovic, the Serbia defender, had given the visitors a first half lead. It could have been so different for the home side had it not been for Thibaut Courtois, the Chelsea goalkeeper.
