Seville - Spain's Rafael Nadal showed his solidarity with fellow tennis stars from Argentina Thursday by slamming the timing of anti-doping controls.
Spain host Argentina in this year's Davis Cup final with Nadal, who finished the season as world No 2, set to open proceedings against Juan Monaco on Friday.
A day prior to the start of the three-day competition Argentina's camp was up in arms, however, after being woken early to undergo anti-doping tests.
"Today was a rest day for us but we didn't get any rest," complained Argentina captain Tito Vazquez.
Nadal, speaking on the fringes of the draw which was released earlier on Thursday, came out in support of Spain's rivals.
"All athletes want sport to be clean, but that's not the way to go about it."
