Emotional Andy Murray dedicated his Davis Cup win over Leandro Riedi to his late gran as he revealed he missed the funeral to compete in the tournament.

The former world number one battled back from a set down to debutant Riedi in a three-hour encounter to claim a 1-0 lead for Great Britain over Switzerland.

And after the match, Murray explained that it was a "tough day" for him as he missed his gran's funeral to play in the match in Manchester.

In a post-match interview Murray was applauded by supporters at the AO Arena as he broke down in tears discussing his grandmother. 

Dedicating the victory to his gran and apologising to his family for being unable to attend the funeral, he said: "Today is a tough day for me. It is actually my gran's funeral today. Sorry.

"So yeah, I am sorry to my family that I am not able to be there.

"But yeah, gran that one was for you. Thank you."

On the hard-fought win over the impressive world number 152 Riedi, Murray added: “It’s obviously incredible to get through that one, it easily could have gone the other way.

“It was ridiculous the shots he was pulling off, amazing, amazing returning. I kept fighting and tried to stay focused and managed to turn it round.”
