Sergio Aguero has claimed that he is only just getting started at Manchester City following a successful beginning to his Premier League career.

The striker has scored 21 goals in all competitions for Roberto Mancini's side this season and is a key component of the club's bid to win trophies both in Europe as well as domestically.

Aguero said: "When I scored twice on my debut I tweeted, 'This is the beginning of something big'.

"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."

The former Atletico Madrid forward also admitted that his form this season has come as a surprise.

"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," Aguero added.

Manchester City will face Sporting Lisbon in the Europa League on Thursday evening.
