Oliver focused on long-term goals

David Oliver can understand the pressure on British athletes ahead of London 2012 and talks through his return from injury and current priorities.

The US sprint hurdler, who has been hampered by a foot injury during the 2011 season, says he has had to change his outlook on competing and is focused on winning gold at this month's World Championships and next year's Olympics.

Oliver, 29, is competing at the London Diamond League event this weekend at Crystal Palace.
