(Reuters) - Roger Federer will be highly motivated to reclaim the world number one ranking for the first time in more than five years when he plays at this week's ABN Amro World Tennis event in Rotterdam.

The 36-year-old Australian Open champion arrived in the Dutch port city at the weekend knowing a run to the semi-finals will move him ahead of Rafael Nadal in the ATP standings.
