Andy Murray is in heaven. Forget the fact that today, weather permitting, he will play his first Grand Slam semi-final, against Rafael Nadal here at the US Open. The Scot is in his favourite city, has breakfast every morning at Starbucks and can spend his spare afternoons shopping with his girlfriend or playing mini-Olympics with his coaching team at the Chelsea Piers Sports and Entertainment Complex on the waterfront. Best of all, a new season of the American comedy series Entourage, his favourite television programme, opens tomorrow night. Indeed if the weather forecast proves correct – a tropical storm was due to hit the city overnight and drench it for the next 24 hours – he could spend most of the weekend watching American TV.
