O'Hara was ineligible for the semi-final against his parent club Tottenham earlier this month but is determined to overcome injury in time for the seasonal showpiece. Back problems have since threatened O'Hara's chances of playing in the final on May 15, but he has given coach Avram Grant a major boost by insisting he will be ready in time. "I've got some bruising on the bone and it got pretty painful," said O'Hara. "It got inflamed where I have been playing so many games - I think I played 15 games on the spin. "I was trying to play through the pain for the past month or so, but it got to the point where I just needed to rest it. "It's not going to be 100% for the final, but I'll go out there on one leg if I have to. I'm not going to miss out on this game." The 23-year-old could return to training either later this week or early next week. "I will try to get myself right," he added. "I'm a bit like a boxer at the moment - I'm resting until two weeks before and then I will really crack on and get myself right for the game."
