Didier Drogba has suggested that winning the Double could surpass anything Chelsea achieved under José Mourinho. The combustible Portuguese enjoyed a brief but glorious reign at Stamford Bridge, winning six trophies in his three years. If Chelsea were to beat Portsmouth in Saturday's FA Cup final, though, Carlo Ancelotti, could boast of having pulled off a feat that eluded Mourinho.

"We never managed it before but all seasons are different," Drogba said. "For instance, with Mourinho we won the title and went into the semi-finals of the Champions League. This one we were out against [Mourinho's] Inter so early but we are going for the Double. You know, seasons are different and they bring different emotions. This one could be special."

The striker admits, however, that it is European coronation that Chelsea still crave and the strength of their yearning may have clouded their focus during the quarter-final defeat by Inter. "I think we want to win the Champions League so much that we sometimes forget to play and put ourselves under a lot of pressure," Drogba said. "If the Champions League wants to come to Chelsea, if one day we are going to win it, then I think one day we'll win it. But we have to take out all the pressure we put on ourselves because we have won everything in England and we want to win something in Europe. Next season is going to be an exciting one. Of course we want to win everything but the best way to win it is to think about it but not too much."

Drogba was nullified by the Brazilian centre-back Lúcio in the games against Inter but overall he maintains that his performances reached new heights over the course of this campaign. "I think this is the best season of my career," the Ivorian said. "In my third season here I scored 20 goals in the league, in this one I scored 29 – it's amazing. I really feel season after season I'm getting better." The 32-year-old does not believe that trend is about to abate. "I always keep working. Obviously I'm not Lionel Messi or Cristiano Ronaldo but I have my own qualities so I work on them and I always try to improve my weak points."

While Sir Alex Ferguson and Arsène Wenger have claimed that the fact that Chelsea have several players other than Drogba in their 30s means they are a team on the wane, Drogba denies that and draws hope from Mourinho's current side. "I would say the team is not getting old, it's getting a lot of experience," he said. "When you see Inter – I think their team is about 37, all of them! And they are in the Champions League final. So it doesn't really affect the team, it's more about the confidence and knowing you can play well. Of course you will lose some games because we are not 25 but it's the right balance to find between young players who are 17 or 18 and older players. There's a right balance to find and I think we've found it."

Drogba has often appeared uncomfortable at Stamford Bridge, notably in the immediate aftermath of Mourinho's departure, when the Portuguese's relationship with the club's owner, Roman Abramovich, deteriorated to the point that the Russian decided to let the manager go. But the Ivorian now says he wants to stay at Chelsea for the rest of his career.

"Yes, because football is important and Chelsea is a big part of my life, I love this club, I really love this club, but there is more important things in life than football," he said. "When I am here I appreciate every moment. I really love this club. My relationship with the fans, with the team is something really unbelievable. We have been together a long time – six years. I am at home. I would love to finish my career here but in football you never know. I said [in the past] I want to finish my career in Marseille and a month later I was at Chelsea. I want to finish my career here, yes, and I hope it will happen."

One player linked with a move this summer is the Liverpool striker Fernando Torres. Drogba said he would be welcomed were he to sign for the Stamford Bridge club. "Of course. Every time there is a new player coming here it's making the club bigger and giving us a lot of strength. If there is a chance for him to come he will be welcome – because any help is welcome."
