NATHAN CLEVERLY says beating Andrzej Fonfara will be the biggest win of his career as the clash at the UIC Pavilion in Chicago on Friday night, live on Sky Sports in the UK and on Spike in the US.

Cleverly is back at light-heavyweight to face the Chicago-based Pole, who is defending the WBC International title he won with a ninth round stoppage against Julio Cesar Chavez Jnr in California in April.

Both men told today’s press conference that they expect the toughest fight of their careers, with the winner of the bout in pole position to move onto fight for world honours – and Cleverly reiterated his desire to return to the top of the pile in the division having landed the WBO World title in 2010 and successfully defending it five times.

“I believe that this is the right move and the right fight for me,” said Cleverly. “There were other options on the table, but I chose to come to America to face Fonfara. I think that this is a great opportunity for me – if I can beat Fonfara we are in the big league then, so this is the most important night of my career. I belong at light-heavyweight, I feel good and confident and I expect to win.

“Fonfara is young, fresh, he has the momentum from his win over Chavez Jnr, and he pushed Adonis Stevenson all the way, so I know that it’s tough but I am ready for it. He has a good resume and he’s done well against some good fighters, but if the best of me turns up on Friday night and I am firing on all cylinders, I think I have too much for him. I am under no illusions that it is a tough fight, but I think that I have too much.

“I’m relatively young in boxing terms, but I have no goals beyond beating Fonfara. My vision is on him only because this is a really big fight, an acid test.

Fonfara is in his hometown and he’s the favourite – I can understand that, but it’s good, it takes the pressure off, I don’t have to sell this fight to the media or do extra stuff like I would if it had been in Cardiff, I am just focused on executing the plan that we believe will get the win.”
