The former world champion returned to the ring on Saturday following a 32-month absence and defeated Albanian Sefer Seferi after four rounds.
Fury extended his unbeaten record to 26 wins, 19 by knockout, while Seferi suffered his second defeat in 25 fights.
"I opted for a bigger opponent but we couldn't really get anybody, there was nobody available".
"I'm going to have a world title by the end of the year".
After beating Wladimir Klitschko for the WBA, WBO and IBF world heavyweight titles, Fury's life spun out of control and he had not fought since.
That's because Fury's ring walk was definitely worth the wait.
"We took Seferi, who had a good record and a tough chin and he took me a few rounds".
Seferi, who was almost five stones lighter and seven inches smaller, did show some ambition early on but Fury's height and movement ensured there was never going to be an upset at Manchester Arena. He needs to get the ring rust off.
His promoter Frank Warren is evidently intent on keeping Fury busy as he begins his long road back towards the top, and he is next scheduled to fight at Windsor Park in Belfast on August 18.
Fury played to the crowd in the first round and looked a bit embarrassed when Seferi tried to rough up the former champion.
By the fourth it became apparent Fury, who sporadically unloaded right hands, could end the fight when ever he wished - but the decision was taken out of his hands by Seferi's corner when they withdrew their man at the end of the round.
"Bomber" took to Twitter after Fury's comeback fight to promise that he would be able to knock out the undefeated heavyweight.
Fury has plans to regain his three world titles, now in the possession of English rival Anthony Joshua, and his one potential future opponent could be Germany's Manuel Charr who was ringside.
But just boxing again seemed unlikely at times for Fury during a troublesome period away from boxing. He received his boxing licence in January after accepting a backdated two-year doping ban.
