The Sweden striker feels the French champions are far stronger and better prepared following another summer of spending and last season's exploits in the competition
The Ligue 1 champions reached the quarter-final stage before being edged out by Barcelona on away goals last season, but the Sweden star believes that experience in the tournament - coupled with another summer of big investment in the squad - has left les Parisiens with a genuine chance of European glory.
Speaking to reporters prior to PSG's friendly match with Real Madrid in Sweden, he said: "The team is even better. Last year, things went well for us in the Champions League. We didn't win it but we still played well. We know better now.
"There are new players who have arrived and will give us more. We won the French championship. We could already start to envisage winning the European cup. This is already a good start."
Laurent Blanc's side have already splashed out around €116 million (£100m) on Edinson Cavani, Marquinhos and Lucas Digne this summer, and have been linked with moves for Daniele De Rossi and Cristiano Ronaldo, too.
