Cape Town - Unai Emery acknowledged the importance of scoring early in Paris Saint-Germain's 4-0 demolition of Anderlecht on Wednesday.
Kylian Mbappe pounced after just three minutes at the Stade Constant Vanden Stock before another well-timed goal, this time by Edison Cavani a minute before the half-time break.
Neymar added his obligatory goal on 66 minutes, with Angel Di Maria rounding off the night with his 88th minute strike.
After the game, the PSG head coach told the club's official website: "It was important to score early.
"Anderlecht are a very good side and created a number of scoring chances in the first half.
"At half-time, we said we needed to control the game better, and that's what we managed to do in the second half. We carved out more chances than them."
Up next for PSG is a Ligue 1 encounter with Marseille, with Emery adding: "Now we turn our attention to the Classico on Sunday. We know that the supporters are looking forward to this match.
"We will do everything we can to prepare well and bring the three points home for the fans."
Mbappe, meanwhile, added: "We want to play well in the Champions League, and that's what we've done so far.
"We are winning well and bringing home another three points. I think we can do even better.
"We played well, but sometimes you have to know how to control a game because we still have a lot of matches to come."
