Manchester City defender John Stones feels they can win the Champions League this season.
City boss Pep Guardiola insists they might not be good enough to challenge for the biggest prize in club football this season.
But Stones, who scored twice in Feyenoord, insists there is nothing wrong with thinking big.
The England ace said: "To come away from home in the Champions League, score four goals and keep a clean sheet is a massive boost for us to take into the next game.
"I've never scored twice in a game, apart from probably when I was about seven!
"I'm pleased with scoring and keeping a clean sheet - that's pleasing for us defenders!
"Everyone was firing and working hard for each other. Credit to everyone - even the players on the bench, who came on and did their job.
"It shows their character – they're willing to do everything when they get the game time.
"We've got a dream and we have to feel confident that we can do it. Why not?
"We want to be in every competition, trying to win things."
