The Davis Cup means so much to Andy Murray that he's thinking seriously about skipping the end of year World Tour Finals in order to prepare for Great Britain's Davis Cup final against Belgium in late November.
The 28-year-old has performed heroics in helping Britain to its first Davis Cup final for 37 years, winning both his singles and a doubles to guide the team past Australia in last weekend's semi-final in Glasgow.
The final will be played in Belgium from November 27th to 29th -- just a few days after the ATP's season-finale at London's O2 Arena for which Murray has already sealed one of the eight spots up for grabs.
Winning the ATP's showpiece would normally be a priority for Murray, especially as he is yet to do it, but his priorities will now be on helping Britain win the Davis Cup for the first time since 1936.
To complicate matters further, Belgium are likely to choose an indoor clay surface, hoping to nullify the effect of world number three Murray who favours hard courts.
"The O2 would obviously be a question mark for me if we were playing on the clay," Murray told the BBC.
"I would go and train and prepare on the clay to get ready for the final.
"If you reach the final (of the O2 event) 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."
Roger Federer faced a similar predicament last year when he played in London just a few days before trying to win his first Davis Cup title with Switzerland in France.
Federer arrived in Lille exhausted and nursing a back injury that meant he had to withdraw from the ATP Tour finals title decider against Novak Djokovic.
He ended up losing easily to Gael Monfils in the second singles, before recovering to win the doubles with Stanislas Wawrinka and his second singles against Richard Gasquet.
Murray complained of back pains during the tie against Australia and the transition from a hard surface to clay has always proved problematic for the Scot.
"I need more time on the clay to let my back get used to it," he said.
Belgium are yet to name the venue and surface for the final but a clay court inside the Flanders Expo Arena in Ghent is the likely choice.
Meanwhile Yannick Noah, the last Frenchman to win a grand slam title, has been named as his country's new Davis Cup captain.
Noah, who won the French Open in 1983, is taking over from Arnaud Clement.
France, champions nine times, were beaten by Britain in the World Group quarter-finals this year.
