The Sweden international scored twice at the Parc des Princes to help PSG register their second successive victory in the Champions League Group C.
"It feels very good," UEFA.com quotes him as saying. "We played a good game and today I was lucky to score two goals, but the team did well and that's the most important thing.
"The individual part comes second; when the team is doing well it's easier [for me] to play. Today I think we kept at a high level; we worked a lot, we ran a lot and we won the game. This gives us a lot of confidence, but we're not losing our heads and thinking too far ahead. The next game is Anderlecht and we're still in the group [stage].
"We've played two games, we've won two games. The door is open now to qualify for the next round, but we're still in the group with difficult games to play and we don't underestimate anybody. This was just a game we played for the group; we took three points today, so the next game will be even more difficult."
PSG are currently at the top of Group C with six points from two matches, three points ahead of Olympiacos and Benfica.
