Matthew Macklin has warned Felix Sturm there is 'no doubt' he will beat his German opponent in next month's world title showdown.
The two-time European middleweight champion addressed his rival in perfect German at a press conference in Cologne, where the fight will take place on June 25.
And Birmingham-born Macklin is relishing the prospect of ending Sturm's reign, insisting he has what it takes to beat the current WBA middleweight champion.
Macklin, known to fans as 'The Tipperary Tornado', said: "I'm going to win, there is no doubt in my mind about that.
"Felix is a great technician, he has been a great champion and he has my utmost respect but this is my time and my strength and power will be decisive in winning the fight."
But while Sturm admits the 29-year-old Irishman is a tough competitor, he remains adamant that he will defend his title after almost a decade at the top of the middleweight division.
Sturm said: "Matthew seems very confident but we will see what happens in the ring. I will bombard him from the first bell and we will see if he can cope with that.
"Macklin is an outstanding challenger. He is very experienced and he has that Irish warrior mentality.
"He has earned this chance and is one of the five best middleweights in the world. It will be a war but I will be ready for anything and I will do whatever it takes to keep my title."
And Sturm's trainer Fritz Sdunek believes his protιgι is prepared for anything thrown at him when the pair enter the ring at the 20,000-seater Lanxess Arena.
Sdunek said: "We have a plan for anything Macklin can present in the ring. We have watched him fight and he likes to put a lot of pressure on his opponents to try to tire them out.
"Felix has no problems coping with that kind of style and putting on a lot of pressure himself so I believe he will stop Macklin in the final third of the fight."Tags: Matthew Macklin , Felix Sturm , Sturm vs Macklin , Sturm-Macklin
