Rafael Nadal's impending retirement will loom over the Davis Cup Final 8 when play begins Tuesday in Malaga, Spain.

Andy Murray says his long-time rival hasn't changed a bit in the 25 years they've known one another. Nadal will look to bring Spain another Davis Cup title - 20 years after he won his first for the nation.

Rafa Nadal said he could skip singles matches at the Davis Cup Finals in Malaga this week and limit himself to doubles action if it helped Spain's title chances in his last tournament as a professional player.
