Anthony Joshua is ready for a fire-fight against Kubrat Pulev as he vowed to be the last man standing.
Joshua was too reckless against Andy Ruiz Jr last summer and paid the price as he was beaten for the first time.
He avenged his defeat 12 months ago to become a two-weight world champion with a disciplined and patient performance.
But Joshua has no doubt that he and Pulev have the ability to end their showdown at any point.
“I’ve been fighting at a top level ever since I went into the gym,” he said.
“I’ve been punched by the strongest people many times ands I’m still here so that never changed me so the loss to Ruiz isn’t enough to change me.
“Every fighter trains hard but it’s character that separates us and I have a lot of character. I’m definitely going to get hit and he’s going to get hit, it will be last man standing.
“I’ve known Pulev for years. I was in Wladimir Klitschko’s camp when he prepared for Pulev so I understand the tactics to beat Pulev.
“I’m prepared to go to the final bell. I’m a 15-round fighter, not a 12-round fighter. I can carry stamina, boxing IQ, concentration and strength until the final bell.”
Joshua was widely criticised following his defeat by Ruiz Jr but bounced back within six months.
And he believes that will stand him in good stead against mandatory challenger Pulev on Saturday night.
“I’ve always fought the best, what have I got to lose? I’ve got everything to gain.
“It’s about taking on challenges and this is another one I’ve got to compete in.
“I don’t want credit, I don’t yearn for it, I’m motivated and hungry; that’s why I put myself forward for any opportunity.”
Pulev was due to face Joshua in 2017 but pulled out with a shoulder injury.
The Bulgarian has fought his way back into the mandatory position, and said: “I have waited a long time. I had [an injury] in 2017. I knew this fight would come again.
“Now I am healthy; I’m not 22 years old, of course, but I am ready now. I have everything to be champion.”
