Manchester City ace Sergio Aguero insists he's yet to hit top gear since his summer arrival from Atletico Madrid.
The £35million record signing has enjoyed an explosive first season at the Etihad with 21 goals already in all competitions.
He said: "When I scored twice on my debut I tweeted, 'This is the beginning of something big'.
"If you had told me before arriving that I would play like I did, I wouldn't have believed you - even though I have always been confident.
"But with so many changes - it was another country, another club, another league, new team-mates and also a new language - I thought it would have taken a little more time to adapt to the club.
"I was lucky, because when I moved to England it was the right moment in my life to do it. I needed a change, you know. I needed to grow up as a footballer.
"But I was lucky too because Man City was a serious club with a huge project. They were a great team with great players. So it was easy for me to adapt myself to the club." "I wrote it because I am always trying to achieve great things. I still feel the same way. I think this is only the beginning for me at City.
