The Ivorian claims he "might not celebrate" should he score against his old side at Stamford Bridge but insists he is determined to reach the Champions League quarterfinals.
Didier Drogba says returning to Stamford Bridge will be "emotional" as his Galatasaray side prepares to take on Chelsea in the Champions League last 16 second leg.
Drogba, who scored the winning penalty for Chelsea in the final of the competition two years ago, will return to Stamford Bridge for the first time since his departure in 2012 when his current side faces Jose Mourinho's men Tuesday.
However, despite spending eight years with Chelsea, the striker has insisted he will do his best to help his current club advance in the competition as it looks to build on its 1-1 draw from the first leg.
"It's very difficult to play against Chelsea, but it's not going to be difficult for me because now I belong to Galatasaray," the Cote d'Ivoire international told reporters. "I need to be professional. Of course there will be emotions, like in the first leg, which was special.
"But I've nothing to prove to this club. Everything I have to prove I did already with Chelsea. I come here with another team and I just want to win the game and qualify. There's nothing personal against Chelsea. There will never be."
"With all the respect I have for this club, for the fans and the players, I might not celebrate. But if we win I will be happy," he continued. "I'm really happy at Galatasaray. And I'm focusing on this game because it's an important one and I want it to be the best one."
The 36-year-old went on to reveal he would find it difficult to turn his back on the game when he opts to call time on his impressive career.
"I've learned so much in football," he said. ''This sport gave me so much as well. I can't turn my back and say I'm going to go into something different.
