Grand Slam titles: 20 (Australian Open 2004, 2006, 2007, 2010, 2017, 2018; French Open 2009; Wimbledon 2003, 2004, 2005, 2006, 2007, 2009, 2012, 2017; U.S. Open 2004, 2005, 2006, 2007, 2008)
2018 ATP match record: 25-3
2018 ATP titles: 3
Biggest weapon: Federer's trademark serve-and-volley game makes him the bookmakers' favourite to seal his ninth Wimbledon title this year. His amazing movement and shotmaking skills combined with his experience on the surface makes him a complete package.
Biggest weakness: Fatigue may hinder the 36-year-old's progress during the latter stages of the tournament, and he must avoid five-setters to sustain a title bid.
2-Rafa Nadal (Spain)
World ranking: 1
Born: June 3, 1986 (Age 32)
Height: 1.85 metres
Plays: Left-handed
