Hibernian manager Colin Calderwood refuses to give guarantees about his future in Scotland, suggesting he could link up with Chris Hughton at Birmingham. New Birmingham manager Chris Hughton, under whom Calderwood worked at Newcastle, and Forest boss Steve McClaren were keen to take the former Scotland defender in an assistant capacity, but Hibs chairman Rod Petrie rejected both approaches. Hughton said last week: "Of course I would like to bring Colin Calderwood here st St Andrews, but that is out of my hands at the moment." Some Hibs fans heckled Calderwood over the uncertainty at East Fife last weekend but the manager, whose team host Barnsley in their penultimate friendly before facing Celtic in the SPL next Sunday, insists there has been no negative impact behind the scenes. Calderwood did nothing to dampen the speculation when it first emerged last month, but he has since been keen to focus on his job. Colin Calderwood: "I haven't heard anything about it for probably 10 days, two weeks. "The group has been excellent. It hasn't touched us at all in terms of affecting training or games. "You come in and do your job, the focus is not on that. It may be for other people but it's not on that for me. So it doesn't touch you as much. "I'm definitely aware that it affects the club and it affects supporters' thinking because they are the ones who are listening, reading and watching the coverage. "But rest assured the work that's going in wouldn't be any different."
