The trainer of middleweight Sebastian Zbik (30-1, 10KOs), Artur Grigorian, expects a very tough fight when his boxer challenges WBA champion Felix Sturm on April 13th at the Lanxess-Arena in Cologne, Germany.

Grigorian is correcting any and all mistakes he felt were committed during Zbik's training camp for last June's twelve round decision loss to Julio Cesar Chavez Jr.

"I've never seen him look so strong in sparring. We know exactly when and how we can use our strongest weapons. We will show [these things] in the fight. I have great respect for Felix Sturm. He is not only champion, but the super champion. He is always well prepared, flexible, and a very good boxer. Therefore, we must give everything [of ourselves] in training," Grigorian said.

"In boxing you sometimes only get one or two chances [at a title]. But now we can't make any mistakes in training, because we must be particularly strong. There are several variants [for the fight strategy]. I know, as a former boxer, that you have to move very quickly [to change your strategy] if something goes wrong. You must always fight so its harder for your opponent, and not for yourself. Then all is well. We respect what Felix can do, [but for every good fighter there is] always a good answer."
