World number two Rafael Nadal has admitted that top players struggle to reach their targets due to the demanding ATP schedule.

The Spaniard has endured a fairly disappointing 2009 in which Roger Federer replaced him as world number one and he battled to overcome a recurring knee injury.
The 23-year-old, who contributed to Spain's Davis Cup victory earlier this month, is now training for 2010 and will get his new season underway with an exhibition event in Abu Dhabi before he turns his attention to defending his Australian Open title.
""I have been training for some time,"" said Nadal.
