George Groves is content to continue learning on the job as he steadily works his way towards world title level.

The unbeaten 23-year-old retained his British and Commonwealth super-middleweight titles by knocking out Paul Smith in the second round at Wembley Arena on Saturday.

The Hammersmith prospect, who is just 14 fights into his professional career, has already proved himself to be the best 12-stone fighter at domestic level.

But Groves admits he still has plenty of learning to do before he can mix it with the likes of sometime sparring partner Carl Froch at the very top.

"I'm content with the belts I've got and I've still got to defend them if I want to keep them outright, which is an ambition I have," he said after stopping former British champion Smith.

"If something bigger and better comes along and it's the right move then 100% I'll take it.

"I'm not in the gym craving something better because I know as long as I keep improving, I'll get there. I don't have to put timeframes on it.

"I've beaten the top guys in Britain so I'm happy to fight the top guys in Europe now and then beyond."

Groves remains intrinsically linked to old amateur rival James DeGale, whom he beat on points as professionals in May.

DeGale bounced back to win the European title but Groves is reluctant to rush into another meeting with the 2008 Olympic gold medallist.

"I've already beaten the European champion," he said.

"I can't keep bashing up poor James DeGale and I can't keep taking the titles he's winning so I'll let him concentrate on improving. In his last fight I didn't see too much improvement.

"I think you saw a different side to me here and my career definitely doesn't revolve around James DeGale. It's about finding fights that are going to help me improve."
