John McEnroe believes that there are some key differences between Nick Kyrgios and the Big Four players - Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray. Not much in terms of technique but mostly mentally. 'He's got some issues with the fear of failure, laying it out there and coming up short', McEnroe explained.
'That is what makes Nadal so great. He's willing to compete and start every match, each match like he hasn't played any before. That's what separates the guys. The guys that are willing to dig in, dig deeper, he's got to find a way to do that.'
About Kyrgios, Chris Evert added: 'Until it gets into his persona, his conscience and his heart, we are not going to see the best of Nick Kyrgios. With the most talented players, when things come very easy to them, mentally they are not tough, because they don't have to be.
It's the grinders that have to work harder that are sometimes mentally tougher. He's got to find that desire and that hunger inside, himself.' In an interview with Vecer, former Croatia's Davis Cup team captain Peter Krajan commented on the new format.
Croatia won its second title ever in the competition last year defeating France in the final. Krajan believes that the top players' appearances are the key to make the tournament successful. 'Changes are needed. I do not know to imagine how an 18-team tournament will be without the support of the local fans. The new event, if there are not Federer, Nadal and Djokovic, has no sense."
