London: Andy Murray conceded his humiliating exit from the ATP Tour Finals was a suitably downbeat way to end one of the most difficult years of his career.
Murray's hopes of salvaging a frustrating campaign by winning the prestigious season-ending event for the first time were shattered as Roger Federer thrashed the Scot 6-0, 6-1 to hand him the joint worst defeat of his career.
The 27-year-old's second defeat from his three group matches was more than enough to condemn him to a premature exit from London's O2 Arena and bring the curtain down on an 11-month tale of woe.
"It's very disappointing. I would have hoped to have done a lot better but when he's extremely loose like he was tonight he was able to try some shots he might not in other situations. Everything he tried came off. He has the ability to do that," Murray said.
"After tonight it's quite clear I'm quite a long way from that level. It's not a nice way to finish the year.
I know I'm going to have to put a lot of work on the tennis court, a lot of work on my game, if I want to start the season with an opportunity to win in Australia."
