Roger Federer and Rafael Nadal are 16/1 to win all four Grand Slams between them again in 2018.
Sky Bet are offering that price about a repeat of 2017 which saw the two thirtysomethings dominate the game, most recently playing out Sunday's Shanghai Masters final which Federer won in straight sets.
Despite having sat out the previous six months, the Swiss, now 36, returned from injury at the start of the year and duly won the Australian Open before later adding the Wimbledon title.
Nadal, 31, captured both the French and US Open crowns to complete the ‘Fedal’ sweep. The duo also managed the feat in 2006, 2007 and 2010.
6/1 is offered that none of the 2018 Slams is won by the world’s top two, who are likely to face a sterner challenge from both Novak Djokovic and Andy Murray next season. Last season’s leading duo spent large chunks of 2017 bothered by injuries.
Two Federer/Nadal titles out of four is the favourite in the market and is offered at 13/8.
Meanwhile, 9/2 is available about the pair contesting the Australian Open final for the second year in succession.
Nadal is the current 11/4 favourite to win in Melbourne in January with Federer at 3/1. It’s 4/1 that Djokovic, who has not played since Wimbledon, captures a seventh Australian title and 11/2 that Murray emerges victorious.
The Briton has also been off the tour since Wimbledon.
