Having made the choice to leave Barcelona, after three years with his home-town club, Fabregas had no shortage of offers to consider.
A return to the Premier League, where he has previously shone for Arsenal, quickly emerged as his preferred option.
A second spell at Emirates Stadium was mooted but quickly ruled out, freeing him to discuss a switch to Stamford Bridge.
Fabregas was impressed by Jose Mourinho and his plans at Chelsea and is of the opinion that he has linked up with a club that is capable of challenging for major domestic and continental honours.
The Spain international told Chelsea Magazine: “I thought, I’m at the right age, I wanted a change and I looked at all the offers I had and – after speaking to the coach – this was the best decision.
“My ambitions are to win absolutely everything.
“The more you win, the more you want to win, although last season Chelsea was not able to lift any trophies, so this season we have to perform well.”
As Fabregas arrived in west London, Chelsea legend Frank Lampard was preparing to depart.
Fabregs is, however, adamant that he should not be considered a direct replacement for the England international.
He added: “I have only just started my career here, but I don’t consider myself to be a replacement for anyone.
“Maybe I don’t score as much as Frank, but I like to assist more. For me, we are different players and cannot be compared.”
Fabregas has made no secret, though, of his desire to inherit the playmaking berth occupied by Lampard for so long.
He said: “It’s true that I have been playing in different positions at Barcelona and I learnt a lot from this as well – it made me a more complete footballer.
“However, I know my place is in midfield –I want to play there and I think the coach knows that.“This is where I think I can give my best. It doesn’t matter if I’m just in front of the defence or playing behind the strikers, they are two positions I really enjoy.”
