Chelsea striker Diego Costa claims he has to be "extra careful" to stay out of trouble because he receives different treatment to his opponents.
Costa returned from a three-game ban for stamping on Liverpool's Emre Can last week and insists he has not changed his style of play. But, in line with Chelsea's belief that the club have been the victims of inconsistency from match officials and the Football Association this season, Costa insists he is a marked man.
"I'm not going to change my way of playing," the forward said. "I do know now that I have to be a little bit more careful because it's not the same when I do something or when someone else does it.
"Something I do, it's talked about much more than another player. I have to be extra careful, but I'm never going to change the way I play. That's what got me here, that's the way I play."
Costa admits that his suspension has set him back and still protests his innocence over the stamp, claiming he does not know why he was -retrospectively banned.
"When I was on top form, when I was at my best, I had that suspension that I still don't even know why it happened," he said. "Now, I'm running a little bit behind, trying to do my best, working hard and, hopefully, I'll be 100 per cent."
Asked if he is still angry about his ban, Costa added: "No. It's gone. Now I'm just trying to get back to my best physical form. You have to forget it."
Costa has scored 17 goals for Chelsea this season, but has not added to his total for four games either side of his suspension. "The truth is I didn't even know how many games it was," he said. "It doesn't worry me. What worries me is to be in the best physical form to score goals."
The 26-year-old is yet to score for Chelsea outside the Premier League, ahead of his first Wembley appearance in Sunday's Capital One Cup final against Tottenham Hotspur.
"I don't pick tournaments to score, or rivals or other teams to score against," said Costa. "I'm a striker, every game I play I want to score. If it hasn't happened in the cup, I'm hoping to God it happens on Sunday.
"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. Playing in a game like this at a ground like this, in my first final for the club, will be very beautiful."
Even though he is looking forward to the occasion, Costa is clear in his belief that Sunday's final will be memorable only if he wins his first silverware with Chelsea.
The pounds 32?million signing from Atletico Madrid is unconcerned that Chelsea lost 5-3 to Tottenham at White Hart Lane on New Year's Day.
"It's an important game whatever way you look at it," said Costa. "What gives it more importance is that it's my first final at the club.
"So I will go in with the mentality and have the motivation to come away with the title.
"I joined a club like Chelsea to win titles. As we say, finals are not to play them, they are to win them. I'm -hoping I can get my first title with Chelsea."
Asked whether the final gives Chelsea the chance for revenge over Spurs, Costa added: "Well, also, we beat them 3-0 first. They are a great side. We deserved that win, they deserved their 5-3 win. There's nothing extra, no revenge or anything like that, just a final and we want to win. Never mind the opposition. We all know we are a good team and we have the quality to win."
Should Costa need help at -Wembley, Chelsea manager Jose Mourinho has the perfect man to call on in the form of striker Didier Drogba.
Drogba has scored an incredible eight goals in eight Wembley cup ties, although his only defeat at the national stadium came against Spurs in the 2008 League Cup.
The 36-year-old netted Chelsea's goal in a 2-1 defeat by Tottenham seven years ago and was on target against Spurs this season in the Blues' victory at Stamford Bridge.
Drogba said: "I've only lost once in a Wembley final and we all know who that was against. But Wembley has been very good to me over the years, so that is the way I would prefer to describe it.
"Put me there on the pitch and you will see what it means to me. If I can make a difference, even if I am only on the pitch for two minutes, I will try to do it.
"This season has been quite a new experience for me and I'm trying to adapt, although my body is not used to making a difference in a short space of time. But if I can bring some luck to the team that way, why not?"
