Organizers of the Mubadala World Tennis Championship say Nadal and Federer will compete at the tournament scheduled to run over New Year's. 

Robin Soderling, Tomas Berdych, Jo-Wilfried Tsonga and Marcos Baghdatis are also in the lineup. 

Nadal won his first title of 2010 in Abu Dhabi. He says the Emirati capital "holds great memories" for him and provides good preparation heading into the Australian Open. 

The tournament runs from Dec. 30 to Jan. 1.
