WBO middleweight world champion Demetrius Andrade has called out Saul 'Canelo' Alvarez for a mega middleweight unification fight.
This comes after the American boxer defended his title against Polish fighter Maciej Sulecki in the USA over the weekend.
Andrade is now keen to face Mexican boxer Alvarez, who is currently holding WBA and IBF super-middleweight world titles.
"Sulecki was a great fighter, a top ten guy who came forward the whole night. He didn't allow me to use my tools," Andrade told Sky Sports News.
"I gave people a great twelve rounds of boxing. I came out strong, utilised my skills and jab. So Canelo where are your cojones at? Let's get it.

"I'm the best out there and if I have to, I will step up to the plate. Like I said, he was a tough, durable guy and was not taking no for an answer," he added.
"He came to fight but I did what I needed to do. I looked pretty - tall, black and handsome. September, let's go.
"Canelo man, let's go. Let's unify this division, one champion. No more running, no more games, let's do it. Let's put it all on the line and see who is the best."
The 31-year-old fighter improved his unblemished record to 28-0 when he defeated Sulecki.
