Davis Cup: Roger Federer plays down Stan Wawrinka row

Roger Federer has played down his spat with Stan Wawrinka, describing it as "heat-of-the-moment".

The Swiss pair are due to play together in the Davis Cup final on Friday.

But they apparently argued as a result of a heated exchange between Wawrinka and Federer's team during Saturday's ATP World Tour Finals semi-final.

"There's no hard feeling whatsoever," said Federer. "We are friends, not enemies, but it was maybe one of those heat-of-the-moment situations."
