On October 28 in Cardiff, English heavyweight champion Anthony Joshua will put through yet another tough test as he takes on Bulgarian Goliath Kubrat Pulev.

The 2012 Olympic medal winner has been taking on a much higher level of opponent in his recent fights, with his legendary bout against Wladimir Klitschko the toughest of all.

Pulev may not be able to match the Ukrainian, but he will certainly test Joshua's credentials, with the Englishman having one eye on a potential unification fight with Deontay Wilder.

Joshua's record speaks for itself since he has turned professional, winning by knockout in every fight and stopping Klitschko in the 11th at Wembley simply underlined his massive future.

But, despite his heroics in London, Joshua has not let his new found status in the boxing game go to his head.

In fact, he has remained humble, refusing to label himself the best in the world and he has even given a surprising opinion about his own boxing ability.

When speaking exclusively to Sky Sports, Joshua spoke about whether he was the most gifted and he said: "I don't think I'm the most gifted - but when you see me fight I think you see my heart. I wear my heart on my sleeve."

I think a few people would disagree with him, particularly as how he has outboxed virtually ever opponent he has met in the heavyweight division.

Klitschko matched him but in the end, his chin stood strong and his ability sealed the victory.

Promoter Eddie Hearn discussed Joshua's future after the bout will Pulev, suggesting that he will take on either Wilder or Luis Ortiz.

"We want the winner; simple as that," Hearn told Sky Sports.

"We'll look at a fight in February or March. That was a key to boxing in October - to box three times next year.

"[Joshua] will have boxed twice this year, next year we'll box February or March, then the summer. If [Joshua vs Wilder or Ortiz] is not February or March it has to be in the summer.

"AJ has got a big job on his hands. I think these are the four best heavyweights in the world now - Joshua, Pulev, Wilder and Ortiz."

However, with Ortiz's failed drug test, it is likely that Wilder will now be the opponent regardless if the fight goes ahead.
