WHO WILL BE the next breakthrough pay-per-view star in America, now that Floyd Mayweather and Manny Pacquiao are counting down the days until they retire?

One boxer hoping to get another crack at becoming a box office star is Saul 'Canelo' Alvarez, the flame-haired Mexican pin up.

Canelo V Mosley

He has already mixed it with Mayweather Jr, losing on points but has bounced back from that defeat with two wins and is ready to kick on and become one of Mexico's all-time greats.

'Canelo' is still only 24, and returns to BoxNation this weekend when he meets American puncher James Kirkland in an assignment fraught with danger.

The former WBA and WBC light-middleweight champion is fearless and fancies his chances against Miguel Cotto and Gennady Golovkin.

But he must impress in this weekend's 12 rounder against Kirkland, if he wants to prove a threat to the best 160lb boxers in world when we moves us.

Besides Alvarez, there are other fighters who ring performance give them crossover appeal.

We take a look at six possible future pay-per-view winners, besides BoxNation favourite Alvarez.

SERGEY KOVALEV (Russia)
32yo, 27(24)-0-1

No Eastern European has ever cracked the US TV market big but Kovalev and Gennady Golovkin have real hope.

Kovalev

Kovalev's heavy handed performances are winning him fans, and his eighth round win over Jean Pascal in March was a licence to thrill.

His best hope of a pay-per-view fight would perhaps be against Andre Ward, if the American can remain busy.

TERENCE CRAWFORD (USA)
27yo, 26(18)-0

The WBO Light-Welterweight champion is rapidly going through the weights, and is one of boxing's fast-emering stars.

Terence Crawford

Slickster Crawford is massively popular in hometown Nebraska and although he'll likely miss out on Mayweather when he moves to 147lb there will be stacks of glamour crushes.

He has come a long way since his BoxNation debut when he stepped in at four days' notice and thrashed Breidis Prescott on points, little more than two years ago.

GENNADY GOLOVKIN (Kazakhstan)
33yo, 32(29)-0

He is fast running out of opposition in the 160lb division having left a trail of destruction each time he steps into the ring.

Golovkin

Golovkin hasn't been the distance for almost seven years, but needs a defining contest at 160lb.

A fight against Mayweather is mentioned, but highly unlikely. There will be pay-per-view chances if Saul Alvarez, Miguel Cotto or Ward tackle him - an opportunity is richly deserved.

KEITH THURMAN (USA)
26yo, 25(21)-0

Florida's Thurman can shoot from the lip and the hip and if he can continue winning in style over the next 12 months his name will soon be up in lights.

Keith Thurman

It has been mooted that he may get a crack at Mayweather before the King of sting retires, and what a golden chance that would be.

There are plenty of high profile match ups at welterweight. Contests against the likes of Amir Khan or Terence Crawford carry appeal.

ANDRE WARD (USA)
31yo, 27(14)-0

But for injury, Ward would be firmly established as a pay-per-view attraction across the pond.

Andre Ward

To many fans he is number two in the pound-for-pound rankings behind Mayweather, when he is active.

He proved himself in the Super Six where he triumphed in the final over Carl Froch, but that was back in December 2011 and he has only boxed twice since.

Ward has his first action since November 2013 when he faces Liverpool's Paul Smith in hometown, Oakland next month.

DEONTAY WILDER (USA)
29yo, 33(32)-0

The WBC Heavyweight World champion still has a long climb to reach the status where fans shell out to watch him on TV, but the potential is there.

Deontay Wilder

If he did get a crack at Wladimir Klitschko the unification would be a pay-per-view attraction in the United States.

Win and the 'Bronze Bomber' would then surely become the heavyweight star US boxing has been screaming for since the days of Mike Tyson.
