Sukur, who also had a spell with Blackburn, said: "Drogba is a top player.
"If he and I were in the same team during my playing years, I don't think we could've played together. We have the same up-front style.
"But I believe both Drogba and Sneijder will make a great impact and bring Galatasaray success.
"Sneijder still needs time as he hasn't played for a while and is just regaining match fitness.
"But they're both really good transfers and hopefully Galatasaray will do great. I wish them the best of luck."
