Manchester City boss Roberto Mancini won't hide ambitions of winning the Champions League this season.
Sergio Aguero hit a hat-trick as City walloped Wigan 3-0 at the Etihad Stadium as a warm-up for Wednesday's Euro opener against Napoli.
Mancini said: "We can say we want to win the Champions League because all the teams who enter it want to win it.
"But for us now it's important we reach the second stage. We're in a hard group where anyone could finish top or bottom.
"Remember the Champions League is different from the Premier League. If you lose a game in the domestic championship, you have time to recover.
"If you lose a game in the Champions League, you don't have that opportunity.
"So it's a good competition but you need some luck."
