They further claimed that Ruud relied on good draws to climb up the ladder, and that his current ranking does not accurately reflect his position in the field."He rarely played top10 opposition is his good runs last year. Capitalized on good draws, current rank does not reflect his true place in the field," the tweet read.Jesper Engelund@JesperEngelund@TennisPodcast He rarely played top10 opposition is his good runs last year.

Confidence is an intangible, there could be something going on behind the scenes we don’t know about. Karatsev, Monfils, Berettini have also massively dropped off (appreciate injury can be a factor)43@TennisPodcast Doesn’t this just highlight the fine margins between the top 100 guys.

He feels, however, that Djokovic and Federer's claycourt achievements do not get enough attention due to the Spaniard's ground-breaking records on clay."Novak and Roger, they are probably the second-best ever claycourt players. It's just that it's never really talked about because Rafa has all these records, so it's tough," Ruud said.The Norwegian then stated that while a player may have a chance against Nadal on grass, that is not the case on clay. He feels there are very few people in the world who can match the Mallorcan's game on the red dirt."You feel like maybe if you play Rafa on grass or whatever, Rafa has obviously won Wimbledon twice, so he is really good on grass, but you feel like, you can at least go out there and smack some winners and make him uncomfortable," he said."On clay, you can't really do that because he has the time to set up his shots, he has the time to play good defence. If he's on it and he's playing well, there is really not much you can do, unless you are able to match his game, which very few people in the world can do on clay," he added.
