Andy Murray is considering sitting out the ATP World Tour finals if Great Britain’s Davis Cup final opponents Belgium opt to play the tie on clay.
Murray won two singles rubbers and the doubles over the weekend as Britain made the Davis Cup final for the first time since 1978 by beating Australia.
Belgium await in the final and will have the home advantage and the right to choose the type of court, with the Belgian Federation choosing the red surface in four of their last six home matches.
The World Tour Finals, which are played on hard courts, is scheduled to finish on November 22 at London’s O2 Arena with the Davis Cup final starting five days later.
The physical demands of playing both were highlighted by Roger Federer 12 months ago, who had to withdraw from the final of the Tour Finals before winning the Davis Cup with Switzerland despite losing his first rubber.
“The O2 would obviously be a question mark for me if we were playing on the clay,” Murray told BBC Radio 5 live.
“I would go and train and prepare on the clay to get ready for the final.
“You saw last year with Roger Federer that the matches at the O2 are extremely tough and physically demanding.
“If you reach the final and play on the Sunday you also need to take time off – you can’t just play five matches against the best players in the world and then not take any days off.”
