Beaten Andy Murray heads off to London early after meeting his Paris match It is a great pity that the theme tune for the ATP World Tour Finals has been changed this year because never before has it been so apt. Normally the O2 Arena reverberates to the Clash's "London Calling" and, in the last couple of days, the great and the good have heeded that call and run away from the Paris Masters in order to settle into their London digs in time for the start of the end-of-year showcase on Monday. The latest to book his last-minute Eurostar ticket home was Andy Murray, who took a little under two-and-a-half hours to lose to Jerzy Janowicz 5-7, 7-6, 6-2 yesterday. For two sets, the Scot appeared to be happy enough to stay in Paris, playing a patient game against the massive Pole but, after missing a matchpoint at 5-4 in the second set, he seemed to have changed his mind. Maybe going home was the better option. And the more careless Murray became, the more Janowicz grew in confidence and, at 6ft 8ins tall, a confident Janowicz is a terrifying sight. Not that Murray seemed to care. He has never been a fan of losing but defeat to a 21-year-old qualifier in Paris was irrelevant compared to the chance to prepare for the Tour Finals and give himself a chance of winning the end-of-year showcase event for the very best in the world. Clearly he was not alone in this view - Roger Federer did not even bother to turn up in the French capital, while Novak Djokovic lost on Wednesday. "A lot of the players will have had slightly different run-ins to the O2," Murray said. Obviously, me and Novak [Djokovic] lost early this week. Roger [Federer] didn't play and then I think the rest of the guys are still here. So, maybe the guys that go deep in Paris, they'll have confidence from having a good tournament but they may arrive a little bit later and might take a while to get used to the conditions. We don't know. So, I'll have to wait and see. I'll definitely need to play a bit better than I did this week if I want to get some wins there. Murray's coach Ivan Lendl will arrive in London today so the prospect of playing better next week is very real for the Scot. It is the end of a very long year so having "Old Stone Face" guiding him through the last few days of the season is just what he needs to reset his sights and summon the last reserves of energy for that final push. By the sound of it, Murray can hardly wait and, as soon as he had finished business with Janowicz, he was planning his weekend practice sessions. "I would have thought I'd go back to London tonight," he said, "and either take a rest day tomorrow or go maybe straight from here to the hotel in London and start hitting some balls as soon as we can. I don't know whether I'll hit tomorrow and then just go start practising on Saturday on the court. I haven't seen Ivan since the last day of the US Open so it will be a good six, seven, eight weeks since I last saw him. It will be good to see him again. The first issue Lendl will want to address is Murray's new habit of losing matches from matchpoint up. In his last three tournaments - in fact, since he last saw Lendl on the night of the US Open final - the Scot has held matchpoints against Milos Raonic, Djokovic and now Janowicz and still gone on to lose. That said, Murray's serving has been, for the most part, extremely good so it is unlikely Lendl will be too concerned should his charge find himself serving for a match next week. "It had nothing to do with my serving why I lost the match today," Murray said. I missed groundstrokes. I need to make sure I'm a little bit sharper when I'm in those positions than I have been the last few weeks. And, with that, Murray was off. London was calling and he could not resist it any longer.
