UEFA Champions League: Mbappe, Haaland Shine In PSG, Man City Wins As Chelsea Lose In Zagreb

Kylian Mbappe and Erling Haaland starred Tuesday as Paris Saint-Germain and Manchester City made winning starts in the Champions League group stage, but big-spending Chelsea suffered a shock 1-0 defeat away to Dinamo Zagreb. Real Madrid rode their luck at times before demonstrating their class to kick off their title defence with a 3-0 win at Celtic despite the loss of Karim Benzema to injury.

Mbappe showed why PSG were so desperate to keep him at the end of last season when he seemed set to depart for Real by scoring both goals in PSG's 2-1 victory at home to Juventus, to launch the French champions' quest for the biggest prize in European club football.

"We played well and we got a win in a tremendous atmosphere at home," Mbappe told Canal Plus.

"We always want to play against big teams -- that's why you play in the Champions League. It's that sort of atmosphere we love; matches like this, in which you have to show character."

The France forward volleyed Neymar's delightful scoop past Mattia Perin in the fifth minute at the Parc des Princes before adding another brilliantly-worked goal midway through the first half.

Substitute Weston McKennie headed Juventus back into the game but PSG held on and are level with Benfica in Group H. The Portuguese side beat Maccabi Haifa 2-0 courtesy of goals from Rafa Silva and Alex Grimaldo.

Pep Guardiola has warned Haaland alone can not lead City to Champions League glory this season, but the Norway striker kept up his scintillating form for his new team with two goals in their 4-0 rout of Sevilla.

"He has an incredible sense of goal. We have incredible numbers in scoring goals, so we want to continue like that," said Guardiola.
