Wasn’t for lack of trying. Played it 9 times, reached SF 5 times. Reached finals twice.No.
WTF is irrelevant. It's a big title, yeah, but it's not meaningful. Otherwise, Nadal would have made sure to win it at one point, like he did with everything else that's worth having on your trophy cabinet.
if not for Djokovic and Federer he’d probably have 4 WTFs by now and it would be among his best non clay tournaments.
does anyone argue that Nadal doesn’t care about the Davis Cup? Yet Nadal played only two more DCs than WTFs. The diference wasn’t in the interest Nadal showed, it was in the results
