Mosley takes on Pacquiao at the MGM Grand on May 7th, which will mark one year since his points defeat to Mayweather. Mosley, 39, is looking to bow out of boxing on a high note, having not won a bout since 2009.

Once discussed as the best pound-for-pound boxer around, Mosley has suffered a steep decline, but still believes he can repair his bruised ego.

“I have to give it my 100% all, give it everything I got, beat Pacquiao, we can do a rematch, fight Mayweather, and I think that’s pretty much it for me,” Mosley told the On the Ropes radio show. “Then I will go off and I will stop helping these young fighters become world champions and get into another side of the business.”

The bout will instead be shown on cable channel Primetime, which has led to claims from Hearn that Khan has “killed” his credibility.

“This whole thing has been a shambles from start to finish,” Hearn told ESPN. “It is commercial suicide. Sky is the most important television station in the UK when it comes to boxing, and in my opinion this has killed Khan’s credibility here.

“I feel sorry for Amir Khan. It was obviously bad news that he had to take a cut in moving from Sky Box Office to Sky Sports 3. He would probably have got 80-to-100,000 pay-per-view buys on Sky Box Office, but he would probably have had 700,000 watching on Sky Sports 3.

“This was the chance to build him again with a much bigger UK audience. I doubt whether he will even get 5,000 buys on Primetime, which has no marketing budget at all for the event.”

After Wladimir pulled out of a bout against Dereck Chisora in April, there were concerns over the Ukrainian’s fitness. It had even been speculated that Wladimir’s brother, Vitali, would step in to fight Haye.

However, Haye told BBC Radio 5 live: “I know it’s Wladimir I am fighting, he is fit to fight and ready to go.”

WBA champion Haye will face IBF and WBO holder Klitschko on 25 June or 2 July.

Khan, 24, takes on McCloskey on April 16th at the MEN Arena in Manchester. A victory for Khan would most probably lead to a unification bout against WBC and WBO title-holder Tim Bradley in the summer.

“I want to prove to everyone how good Amir Khan is,” Khan told BBC Sport. “Not only in England, but all over the world.

McCloskey told Sky Sports: “I’m completely different to Pacquiao, Manny’s an aggressive, come forward boxer who punches in bunches. I’m a slick mover, a thinker.”

Ariza, known for working with boxers such as Manny Pacquiao, helped Khan bulk up with a mix of supplements and power shakes. But now Khan is working with Michael Vale, who prefers a more organic approach.

“It was nothing big,” Khan told The Observer. “At the end of the day, we just grew apart. Also, he was with Manny at the same time, and I needed a full-time conditioner.”

Khan is currently in the Philippines training for the fourth defence of his WBA light-welterweight title against Irishman Paul McCloskey in Manchester on 16 April.

If successful, a possible unification fight against Tim Bradley could be scheduled. It has already been rumoured to have been decided to take place on July 23rd in Las Vegas

Amir Kahn has not enjoyed the success that many thought he would after turning pro in 2005, but his popularity is undeniable. McCloskey may not be a huge name, but he will prove a stern test for Kahn, who will want to put on a show for his growing number of supporters.

Kahn has parted company with conditioning coach, Alex Ariza, the man credited for much of his recent success. However, he does not think this will affect the McCloskey bout. Kahn is the overwhelming favourite, but the tricky Irishman is more than capable and may just spring a surprise in what is expected to be an exciting fight.

With the exception of the Champions League final, El  Clasico is perhaps the biggest club game in the world. It also rarely disappoints. The reverse fixture earlier in the season resulted in a 5-0 thrashing for Real Madrid, including David Villa bagging two goals for Barcelona, inflicting a first defeat for Jose Mourinho since he took over at Real.

Mourinho will be eager to get revenge, especially at a time when Barcelona look a little less invincible after their Champions League loss to Arsenal and a lumbering, albeit victorious, performance at home to Athletic Bilbao. Barcelona still lead Real by five points in La Liga, so a win for Mourinho’s expensively assembled side will be vital in keeping the title race open.

Tickets are available for both events now.

Amir Khan will defend his WBA world light-welterweight title against Dimitry Salita on December 5.

The bout will be Khan’s first fight since he won the title with a unanimous decision against Andreas Kotelnik at the MEN Arena, Manchester in July.

The former Olympic silver medallist will be taking on the Ukrainian boxer at the Metro Radio Arena in Newcastle and would be well-advised not to take the bout lightly.

Salita has an unblemished record with 30 victories in as many fights in his professional career with 16 knockouts. Although he may not have a particularly high profile in the wider boxing community he will be keen to upset the odds by handing the Bolton man the second defeat of his career.

Khan is unlikely to be complacent though after he was taught a salutary lesson by Breidis Prescott in June last year. The heavy-hitting Colombian was seen as Khan’s first real test since joining the professional ranks amid criticism that his promoter Frank Warren had been hand-feeding his charge sub-standard opposition.

After just 54 seconds Khan had been knocked out, dismantled by his more experienced opponent. A glass jaw and lack of defensive nous was cited as the reason for his spectacular defeat and legendary trainer Freddie Roach was brought in to rescue the young pugilist’s career.

Khan has responded well to Roach’s teachings and certainly looks a more rounded boxer than the one that entered the ring against Prescott.

Whatever happens, it will be a fight not to be missed.
