Goodnight - but stay tuned for the tennispublished at 18:30 Greenwich Mean Time 13 November 2014
We at team Sportsday are signing off now but do not go anywhere, for right here on the BBC Sport website, from 7.30pm, we have live text commentary of Andy Murray's crunch-match with Roger Federer at the ATP World Tour Finals in London.
The match is also on Radio 5 live sports extra.
Murray needs a straight sets win to make it into the semi-finals. Could be tense. Enjoy and see you again tomorrow from 8am.
