George Groves insists he is not ready for a world title shot - despite destroying Paul Smith in two rounds to defend his British and Commonwealth super-middleweight belts.
Groves extended his unbeaten record to 14 wins with the 11th career knockout.
The Hammersmith fighter said: "I have cleaned up the domestic level but I'm not ready for world level fights.
"It's up to me to improve. It [a title shot] is going to come sooner rather than later."
The defeat was the third of Smith's 34-fight career and the Liverpudlian admitted he may move back down to middleweight in future.
Smith was knocked down early in the second round and, after beating the referee's count, he was floored again almost immediately with a chopping right hand which left the referee no option but to end the contest.
Groves added: "I want to chip up that ladder towards world titles but I need to make more improvements.
"I would like to think I can go all the way to be a great fighter. I plan to get to the top and stay at the top.
"I'm fortunate enough to be in an exciting division. Super-middleweight has some great fighters, so there are loads of great fights I can have in the future."
Groves has tested himself against some of the biggest names in the division by sparring against the likes of current WBC world champion Carl Froch - and American Andre Dirrell.
He admits that a fight against Dirrell is a very real future prospect.
Groves said: "I want to finish top of the tree. I want to be one of Britain's best boxers, one of the greats. I've got it all to do but I know I can do it and I look forward to the challenge."
