Thiem is a good player and he's got the potential to win grand slams but he's gotta up his game. Nadal is effectively the GOAT on clay so it's not easy for anyone to beat him, but Thiem has the speed and hits hard, but can he sustain this for 5 sets at Roland Garros?
I'd love to see Wawrinka snag another GS, but in all honesty, it's time for the youngsters, the guys 25 and younger to make their mark and win or at least get to the finals of the slams, it's been overdue for some time now. With all the respect to the top guys, it would be great for the game if a younger guy won it, or anyone else for that matter that isn't named Federer, Nadal, Djokovic or indeed Murray and Wawrinka. The last one that's not part of the top 5 (and interestingly, it's these five guys that make up the top 5 rankings: Murray at 1, Djokovic 2, Wawrinka 3, Federer 4, and Nadal 5) that won a slam was Del Potro at the 2009 US Open. Before that it was Safin at the 2005 Australian Open, so the beginning of the season in 2005. That's a long time for only a handful of men to win slams. The guys that are consistently in the top echelon, Berdych, Tsonga, Ferrer, are losing steam, and Ferrer more quickly than the rest, but let's be honest, he's 35 and physically he can't run down every ball like he used to. Cilic is way too inconsistent, Raonic and Nishikori have injury issues, especially Nishikori, Gasquet has wasted a lot of his talent and he is already in his 30's, Dimitrov is overrated, Kyrgios...not really sure what to make of him, Zverev has the upside....Really it's time for new champions, both on the men's but the women's as well. Federer, Nadal, Williams, Djokovic are all good for the sport, but it's also good of the sport if someone else comes along and starts winning.
