"I can confirm that Roger is in Serbia and will play in the Davis Cup," Swiss Tennis Federation spokeswoman Sandra Perez said.
               
With Federer renewing his Davis Cup partnership with Wawrinka, the Swiss will start as strong favourites against 2010 winners and 2013 runners-up Serbia, who are missing their top three players including world number two Novak Djokovic.
               
Federer, the winner of 17 Grand Slam titles on the men's ATP Tour, has never won the Davis Cup and renewing his partnership with Wawrinka should present him with a good chance of adding to his jam-packed trophy cabinet.
               
The 32-year-old Swiss maestro last played for his country in the 2012 World Group playoff win over the Netherlands and his best result in the competition was reaching the 2003 semi-finals.
               
Although Wawrinka is likely to be exhausted after his celebrations and a long-haul flight from Melbourne following his win over Spain's world number one Rafa Nadal in Sunday's final, the Swiss should be too strong for a decimated Serbian side.
               
That is, unless world number two Novak Djokovic follows in Federer's footsteps and makes a last minute U-Turn, having earlier pulled out of the tie to focus on the ATP Tour and his bid to wrestle the top ranking spot back from Nadal.
               
If there is to be another twist, Djokovic would have to cut short his skiing holiday in the Serbian resort of Mount Kopaonik, where he has been photographed by local media with friends and family.
               
Serbia will certainly miss the injured Janko Tipsarevic, who has been sidelined with a heel problem since October, and suspended Viktor Troicki who is serving a 12-month doping ban for missing a blood test in April.
