Juventus coach Massimiliano Allegri was full of praise for his players after a well-deserved 2-1 win away against Manchester City.
The Bianconeri struggled in their first three games of the Serie A but bounced back with a brilliant display of football at the Etihad Stadium.
They lead the group together with Sevilla who were 3-0 winners against Borussia Monchengladbach on Tuesday night.
"The lads deserve massive credit for this because it was no mean feat," Allegri told Mediaset Premium Sport.
"We gave away very little tonight. The only saves Buffon had to make came when we lost the ball in midfield in the first half - when we really should have done better in the final third ourselves.
"We deserved to win it but football is a funny old game. First Gigi [goalkeeper Gianluigi Buffon] was superlative and then we went and scored. We just kept believing.
"We've been creating loads in Serie A but haven't been able to convert our chances into wins. It will take a little time – I've only been working with this group for a week. But looking at how we played against Chievo and what we did tonight, I'd say our prospects are good.
"Compared to the Champions League, there's less space in Serie A and you need to be more careful."
