Zlatan Ibrahimovic has challenged Paris Saint-Germain to build on their 4-1 victory over Dinamo Kiev in the Champions League.
The Swedish striker opened the scoring for his new club in the French capital but believes that Carlo Ancelotti's side need to keep their focus if they are to progress in the tournament.
Ibrahimovic said: "It was a first game, it was hard, we won but we must continue to work hard. This is a good signal for the future. If we won, it's because we played well.
"This gives us confidence for the next game against Porto, which is a quality team. This is a wonderful start."
Ibrahimovic broke a Champions League record against Kiev by becoming the first player to score for six different teams in the competition.
