INDIAN WELLS, California (Reuters) - Four-times champion Roger Federer was delighted to welcome back to the ATP Tour his long-time rival Rafa Nadal, a man he could face in the quarter-finals of the BNP Paribas Open at Indian Wells.
Spaniard Nadal has slipped to fifth in the world rankings after being sidelined for seven months last year due to a left knee injury and is seeded to meet Federer in the last eight of the elite ATP Masters 1000 event in the California desert.
