Paris Saint-Germain coach Unai Emery believes Barcelona may be "more dangerous" after Luis Enrique's announcement that he is to step down.
Luis Enrique will leave Barcelona at the end of the campaign, earlier this week citing a need for rest as the reason for his departure.
While Barca may win La Liga and the Copa del Rey, they trail PSG 4-0 in their Champions League last-16 tie ahead of Wednesday's second leg at Camp Nou.
However, Emery feels Luis Enrique's announcement may yet make the return leg trickier for his team.
"Maybe they are now more dangerous," he said after PSG edged Nancy 1-0 in Ligue 1 on Saturday.
"It doesn't change their game or what this game is though. After the result here, to keep the same level over there is going to be very difficult.
"They have to work to overcome the first-leg result and they have the qualities for that. They have players who are used to playing very tough games and are able to overcome the result.
"That's why we need to prepare well, to be mentally ready, to realise it's going to be tough for 90 minutes.
"We need to work well to overcome the complicated part of using the result of the first leg. But we have to be ready for the next 90 minutes.
"It is a game to enjoy, it is a beautiful fixture for the Paris fans, ourselves, the club. We want to play that game."
Barca will go into the clash in goalscoring form, having netted 11 times in their past two games – including thrashing Celta Vigo 5-0 in La Liga on Saturday.
