I have been at Chelsea for a lot of years. I have played in the Premier League, the Champions League, it is a kid's dream to play for Chelsea. I have moved on, who knows I might one day go back to Chelsea.
I definitely want to be successful in the Champions League, having never been involved in it before. It's where the best players prove themselves.
I didn't want to go to Chelsea, because I wanted to play the Champions League and they were sixth in the league.
I have been able to fulfil nearly all my ambitions at Chelsea. I have won the Champions League, the League, I have won FA Cups here, but you don't want to stop winning trophies, and being at a big club, you are always fighting to win a trophy.
Chelsea are champions of Europe, and there is not much more to say than that. Even after winning the Champions League, they still go and sign players of the highest quality. Their ambition is clear.
If I had a choice between the Champions League and the Golden Boot, then of course it would be the Champions League - no doubt the Champions League.
We know how important both competitions are, especially the Champions League since it's such a special competition, but we want to win the league too. We take it game by game - concentrate on our league games, win them and then start thinking about the Champions League.
With Chelsea, the job was this: move up to the top, get into Europe. And I did that - fourth place in the Premier League and then into the Champions League, the season before Abramovich and all the money arrived.
I'm ambitious, I want to play in the Champions League, and that's the aim with Tottenham - to start qualifying for the Champions League on a consistent basis.
Messi doesn't have to do it in the Premier League to prove himself. The Champions League is the ultimate club competition. If he was in the Premier League, he'd be the best player by some distance.
I cried after the game when we won the league - it was hugely special to me. The first season we came second and got to the Champions League semifinal, and I knew I needed to come back and win with Chelsea.
Chelsea belongs in the Champions League, and we must stay there.
All of Europe's biggest clubs place the Champions' League as their top priority these days but only one of us can lift the trophy. The domestic league titles are still crucial of course, but I think most players will tell you the Champions' League is the one they want to win most of all.
When Chelsea came to me and said they wanted me to come back, I was happy because I had a special moment here - one of the best in my career. I won the Champions League, the Europa League.
It's all I've dreamt winning a trophy with Chelsea. To go all the way in the Champions League.
I came to Chelsea and it was 'oh you can't play Champions League, you can't do this, you can't do that' and I proved them wrong.
