I give no quarter, and I ask for none. Out there, I'm going to fight for my team and do the best I can.
Diego Costa
In life, anything can happen, and I do not close the door to anything.
Goals are what count for me. It's not about a battle with defenders. Fighting hard, giving everything and working hard on the field you have to combine with the goals you score. It doesn't matter if defenders want to battle with me or not; I will just be trying to do my job as well as I possibly can.
Don't put wings on me; I am no angel.
I train all week just to play for 90 minutes. I love playing games, and so during those 90 minutes, it's always 100 per cent.
I've done everything to come back to Atletico, but I wouldn't fight the same to return. When Atletico didn't wait for me, I had to go to Conte with the tail between my legs.
If you do not have the team behind you, then you can't do things on your own. It all depends on the team.
If I change in any way, I'm not going to be the same player.
I think anyone in life, everyone in the world, no matter what work they do, they should think of wanting to get on, to win, improve.
Afterwards, when the match is over, I have my family and my friends. I have fun like a normal person.
It's important to be right physically.
I consider myself a player who fights and gives everything on the pitch. Those who know me and appreciate those values understand what I say.
I'd rather have someone who tells me straight up what happens rather than sweet things that I want to hear.
I have to be extra careful, but I'm never going to change the way I play.
I haven't done great things for Spain - I can't lie - but when I play well, they should say so. They criticise me for my character, but I also have quality.
Always, when things don't go the way that everyone expects, people - the supporters as well - always look for someone to blame. In some cases, they blame the players.
I think that football has always had a passionate, aggressive side, with players giving their all. People have to get used to this.
When a game comes around, that's the time to be serious. During the week, the training sessions are serious, but away from there, you have to relax and switch off.
The bottom line is that sometimes the little things I do on the pitch provoke exaggerated reactions.
The truth is I'm fairly relaxed.
Scoring goals is scoring goals. From a striker's point of view, the aim is the same.
In Brazil, if you have a son, the first thing you give him is a football. That's the first gift - so my dad was no different.
Do I enjoy the aggression of English football? No. I like to play football. I like to score goals. I like to do things well.
I don't need to hit people in order to play good football. I'm not a boxer after all.
I want to win and always have done since I was small. I don't know if it's in my blood or just my personality.
I am Brazilian, and that is not going to change, but I want to win the World Cup with Spain.
You just have to be prepared because in the Premier League, you are not always going to have more than once chance to score. When it comes your way, you have to be ready to take that chance. If you're not calm, you know it might not come again.
Every striker has their way of playing and their strengths and a different team behind them. That is very important.
Life has many turns.
Everyone has to be their own critic.
As we say, finals are not to play them, they are to win them.
I joined a club like Chelsea to win titles.
I started playing football on the streets; I grew up playing football on the streets with my friends, and that's why I was brought up the way I was. That's the school I had - the street football.
We always have to show our character on the pitch, and I show my feelings.
Sometimes I even tell my relatives and my friends that I get a lot of love from the fans, and I'm not sure if it's deserved.
Wembley is a ground with great history. It's hosted games and players of great prestige. It's always important playing on great stages like this.
My mindset is always to be victorious, to win the match.
The best way to attack is to defend well.
I have a go at defenders, and they have a go at me. We argue... Whatever happens on the pitch stays on the pitch.
Jose Mourinho has been really clear about what he expects from me, saying he wants me working hard rather than just scoring. Hard work is what he values.
I have to be scoring goals and playing well to get in the team because, if not, others who are in better form will play.
What worries me is to be in the best physical form to score goals.
There are managers who always say what people want to hear. I think that's not good.
I wished I could go back to Atletico; I'm not going to lie.
I think it's really important for managers to be liked by his players because ultimately, on the pitch, those players will give everything for their manager.
I don't have a problem with any defenders. I've always played against great defenders.
A season is very long, and there will be periods where you'll be very good and moments where you won't be as good.
I can only watch calmly if the match is decided or my team are dominating. But I get passionate very easily.
Many times players have done stuff to me, like kick me. But I'm not a cry baby.
I have always seen Drogba as the example to follow in terms of a centre-forward. He was strong and scored loads of goals, and he was a quality player.
