Chelsea legend Didier Drogba says PSG must be patient with their Champions League ambitions.
Drogba, speaking with Telefoot, says PSG president Nasser Al-Khelaifi must not lose hope after another failure this season.
He declared: "It takes time to win a competition.
"Look the teams are not the same, the conditions are not the same. But the determination was on our side (at Chelsea).
"It is also on the Parisian side. But it takes time."
