STUART FRASER: Andy Murray admitted he felt it best that his team did not sit courtside during his straight-sets defeat by Stan Wawrinka at the ATP World Tour Finals on Friday. World No 2 Murray was knocked out in the round-robin stage at The O2 as he lost what was effectively a quarter-final shootout 7-6 (7-4), 6-4 to Roland Garros champion Wawrinka. Eyebrows were raised at the start of the match when it was noticed that Murray's courtside player box was completely empty, with his team - including wife Kim and coach Jonas Bjorkman - sitting together in a higher position well away from the court.
