Cape Town - Paris Saint-Germain coach Unai Emery is taking little for granted despite taking a 4-0 lead in their Champions League clash with Barcelona.
Angel di Maria scored twice at Parc des Princes along with Julian Draxler and Edinson Cavani, giving PSG a healthy lead in their two-legged Round of 16 tie.
"I'm very cautious with the next game," Emery is reported as saying by Marca. "We have to try to continue in the same way.
"It is a great motivation to play against Barcelona, and a difficulty.The game leaves a good taste in the mouth, but you have to be careful because we have 90 minutes to play.
"We have overcome them and we have made a very complete game. We have to try to maintain the level of concentration because their game is very varied."
The former Valencia and Sevilla boss knows all too well the difficulty of beating Barca, and warned that they "have only played 90 minutes" of the tie.
"It was a good game and we now hold a good advantage," Emery added. "Barca are very strong and they will still be strong at Camp Nou. We will be made to suffer there. We must go there thinking that the match has been reset to 0-0."
While birthday boys Cavani and Di Maria grabbed all the headlines for their goals scored Adrien Rabiot turned in a dominant display against the Barcelona midfield as Andres Iniesta and Sergio Busquets were second best the entire game.
The 21-year-old Rabiot capped a fine display with a nutmeg on Messi that summed up Barcelona's evening as they look to be heading out of the Champions League at the last-16 stage.
The last time the Spanish giants failed to advance past the last-16 stage were when they were knocked out by Liverpool in the 06/07 season.
