• Murray beaten 6-3, 6-4, 6-1 by Grigor Dimitrov in second round
• 'It’s unbelievably challenging to play at the highest level’

Andy Murray said that he may need to accept that the deep runs he believes he is still capable of may not actually happen after he suffered one of his most disappointing defeats of the year, losing 6-3, 6-4, 6-1 in the second round of the US Open to Grigor Dimitrov, the 19th seed, at Arthur Ashe Stadium.

“Maybe I need to accept that [at] these events, the deep runs and everything that I felt like I’m capable of, they might not be there, as well,” he said.
