Paris Saint-Germain midfielder Lucas Moura believes that Cesc Fabregas and Didier Drogba could prove to be the difference when his side face Chelsea in the first knockout round of the Champions League.
The sides faced each other in the quarter-finals of the same competition last season; the French champions won the first leg 3-1 but were knocked out on away goals after a Chelsea comeback.
The Brazilian believes that the Blues' summer signings will cause problems. He said: "We will work hard to win these matches. I believe in my team. You have to respect Chelsea. We are very strong, we can win and we will work for that.
"Compared to last season, Chelsea have changed more than us. They are very strong with Drogba and Fabregas."
The Brazilian is right to be concerned. Fabregas has enjoyed some excellent form since his summer move to Stamford Bridge from Barcelona with three goals and 15 assists in 21 appearances including two goals and four assists in the Champions League.
Drogba has been less prolific since his return to England but has still managed six goals in 19 appearances.
PSG president Nasser Al-Khelaifi however is pleased with the draw: "Chelsea is a good draw for us. I am very confident. I trust my coach and my players to display the best of Paris Saint-Germain.
"We learned a lot from the experience of last season, and we will work to have a different ending this year."
PSG finished behind Barcelona in their group and could also have faced Real Madrid, Bayern Munich or Borussia Dortmund. The French side have also changed their squad since last season with the most notable acquisition being that of David Luiz from Chelsea for £40 million during the summer.
