German boxing legend Dariusz 'Tiger' Michalczewski has warned Arthur Abraham (33-3, 27 KOs) to stay focused on Saturday night in Kiel. The WBO's European super middleweight champion will defend his title at 168-pounds against former EBU king Piotr Wilczewski (30-2, 10 KOs). Michalczewski consider the Polish fighter to be a very good boxer, and those kind of fighters present the most problems for Abraham.

"Wilczewski is a good [fighter], who can box. Arthur should definitely not underestimate him. I don't think Abraham can become a world champion. He is inferior, physically, to the other boxers who are [the best in the world]," Michalczewski said.
