Boxer Joe Calzaghe has ruled out a return to the ring, saying it was "time to turn the page and move on".

The undefeated world super-middleweight champion, who hung up his gloves last month, said he had nothing left to prove.

"People think I'm coming back but I can tell you now that's not going to happen," the 37-year-old said.

"I'm pretty happy staying out of the ring. I've done everything I want to do in boxing so it's game over."

Calzaghe's final two fights saw him step up to light-heavyweight, beating Bernard Hopkins on a split decision followed by a comprehensive victory over Roy Jones Jr.

Hopkins has called for a rematch but Calzaghe dismissed the idea.

"I've got Bernard Hopkins offering me big money but if you are just motivated by the money that's when you are going to get hurt," he said.

"He says it's unfinished business but it's only unfinished business for him. He just has to live with the fact that he lost, which is tough."

Calzaghe, who went unbeaten over 46 professional fights, feels he always had the psychological advantage over Hopkins, who is now just after another payday.

"I'm very strong mentally. When you look in somebody's eyes you realise if they are afraid or not afraid and I think he realised he couldn't intimidate me," he added.

"In that fight he knew he had no affect on me. I told him that. I smiled at him and said 'Listen, you're going to get your a**e kicked tomorrow'.

"I didn't fight the best fight that time and I still won.

"I'm happy, I'm content, it's time to turn the page and move on."

Asked if there was anything at all that could tempt him back, he said: "No there is nothing.

"In my weight division there are no great fighters. The biggest fights are with the ones I've already beaten."

But he added: "I'm still training, I'm still keeping fit."

Asked about his thoughts on boxing, he said: "I love boxing, I'll always love boxing. But there's too much politics involved in boxing, there are too many titles.

"The general public lose track of who the real champions are.

"The first thing you should do is get all the champions to fight each other and have one recognised champion in each weight.

"It's too complicated, it's becoming ridiculous."

Calzaghe backed Ricky Hatton to beat Manny Pacquiao when the two meet at the MGM Grand in Las Vegas on May 2, saying he stood a better chance than when he fought Floyd Mayweather.

"It's going to be a tough fight for Ricky but he's got a better chance of beating Manny than against Mayweather," he said.

"Ricky definitely has height advantage so if he can close the range and cut him down he has a great chance of winning.

"He's got to take his chance. You've got to go for it, plus you can make a fortune."
