John Stones feels like a weight has been lifted off his shoulders since he joined Manchester City, where he feels he is working with "the best manager there is".
Stones became the most expensive defender in Premier League history when Guardiola brought him to the Etihad Stadium from Everton for a reported £47.5 million.
And the 22-year-old is happy with how quickly he has settled in at Pep Guardiola's side.
"I feel like there is a weight off my shoulders," he told reporters. "It's nice to be settled and enjoying my football, the new experience, playing in the Champions League and all the things you dream about when you start playing football.

"I feel like I've settled in quickly. It's all come thick and fast and I've been taking in a lot of information over the last few weeks, trying to figure everything out.
"I'm under the best manager there is and I'm just really enjoying myself."
The former Everton player will be rewarded for his strong early season form at club level when he starts in Sam Allardyce's first game in charge of England on Sunday.
And while the centre-back is happy with his development in a short space of time, he continues to evaluate and think about his game as he looks to improve.
"I believe I have come on quite a lot, already, as a player," he said.
"I was doing things before and then I would think: 'Why have I done that? Why haven't I just put it out in row Z?' Already I can see a difference in my decision making.
"So, of course, I'll kick it into row Z if necessary. We can all regroup from putting it in row Z sometimes.
"I've always liked taking the ball out of defence and I will carry on doing that but at the end of the day I'm a defender, and that's what I want to be known as – a defender, getting in the blocks and the headers that people don't recognise I do, the dirty stuff that every defender should do and should be good at. The rest of it is a bonus, where I can play out and start attacks.
"But I know I have to evaluate myself, watch things back and realise when I can do things and when I can't."
