Klitschko unified the WBO and IBF titles against Ibragimov in February
Wladimir Klitschko has promised to give David Haye "a lesson in the ring" - if he proves himself at heavyweight level.
Klitschko, 32, defends his WBO and IBF titles against American Tony Thompson, 36, on Saturday in Hamburg.
Cruiserweight king Haye, who has moved up a division, riled the Ukrainian when they met earlier this year and has called the heavyweight scene "a joke".
But Klitschko warned Londoner Haye, 28, that he is in "a line of people who want to fight me".
He added: "When we met he was overloaded with energy, he was aggressive and very offensive - I think we will have to teach him how to behave himself."
The 6ft 6in Klitschko (50-3-44 KOs) faces Thompson five months after taking the WBO crown from Sultan Ibragimov with an uninspiring win in New York.
Washington DC's Thompson (31-1-19 KOs), who measures 6ft 5in, last year claimed the scalp of Ibragimov's cousin, Timor.
Not known as a big puncher, he is a southpaw whose steady but unspectacular style could cause Klitschko problems.
However, the champion said: "I'm right now in my prime time in the sport.
"I've heard before that the beginning of the 30s, mid-30s, is the best time for heavyweights, and now I know it.
"My mental and physical abilities are in their prime and I enjoy (being in the ring) a lot."
