Ahead of this week’s David Cup semi-final against Argentina Andy Murray has said that recovering from his US Open disappointment will be tough.

Murray was favourite to claim his fourth grand slam title at Flushing Meadows but he was beaten 1-6 6-4 4-6 6-1 7-5 by Kei Nishikori in the last eight of the tournament.

The world No 2 must now forget about his disappointment and focus on Britain’s Davis Cup match against Argentina which is likely to see him play two singles rubbers as well as doubles.

Murray had just eight days to fly home and recuperate ahead of the net match in Glasgow and he has said that he will need to make the most of his time off.

While he has every reason to be disappointed he said that he is looking forward to the match and that “it should be a great, great atmosphere, a great occasion”.

He said that ideally he would have a little more time off but that he will have it after the Davis Cup is done and in the meantime he needs to be “smart” as he will need a lot of energy for the upcoming matches.

He said that he needs to recover physically and mentally ahead of what is sure to be “a stressful few days.”

His five-set defeat to Nishikori will have been particularly exhausting. He twice led the Japanese by a set and his loss was at least partly his own fault. He lost seven games in a row after his break point in the fourth set had to be replayed due to a loud noise from the stadium’s malfunctioning sound system. The incident saw Murray react angrily and lose focus.

Nonetheless, he has had a good summer winning Wimbledon, an Olympic gold medal and reaching seven consecutive tournament finals.
