Like Rafael Nadal on clay, it would seem Roger Federer faces little in the way of resistance as he aims for his ninth Wimbledon title. But looks can be deceiving.
Here are the players who are must likely to ruffle Federer's feathers—or at least stand a good chance of facing him in the final.
1
Rafael Nadal
Nadal is the King of Clay but he's still a dangerous threat on grass. The Spaniard has won two titles at Wimbledon, in 2008 and 2010. It's been a long while since he's won in white, but it's tough to count him out.
2
Marin Cilic
It’s time to stop taking Cilic for granted and acknowledge him as the threat he is. The Croatian has won the US Open and appeared in two of the last four major finals, after all.
