Radcliffe aware of O'Sullivan threat

England's Paula Radcliffe chases a second major gold in nine days as she bids to add the European 10,000 metres crown to her Commonwealth 5,000m title tonight.

Radcliffe is looking to wipe out the distant, but haunting, memory of four years ago when, in only her second race over 25 laps, she finished a disappointing fifth in Budapest.
