Klitschko said his next opponent is likely to be Britain's WBA heavyweight champion David Haye or Ruslan Chagaev.
"I was in good form, Sosnowski was younger than me, but people saw that I did well against him," reflected Klitschko, who at 38 was 17 years his opponent's senior.
"He did everything to win this fight, but my experience got me through."
That seemed a fair assessment from the Ukrainian who physically did not look at his peak against the European heavyweight champion.
