Great Britain's Joe Salisbury and Neal Skupski will chase a slice of tennis history in Sunday's ATP Finals doubles trophy match - but a fellow Briton across the net will be out to stop them.
It has been said that the final will be the last outing as a team for Salisbury and Skupski, before they move on to new partners for 2026, and on that basis it presents an ideal chance for them to part ways on a high.
No British team have ever won the doubles title at the season-end event, although Salisbury has twice been a champion alongside American Rajeev Ram.
