Murray fit for Davis Cup tie

Andy Murray has declared himself fit for this weekend's crucial Davis Cup relegation play-off against Poland in Liverpool.

The Scot had been carrying a wrist injury from the US Open but is confident he will be able to lead Great Britain in their bid to remain in Group 1 of the Europe-Africa Zone for the next year.

"I practised on Monday for the first time since the US Open so I should be okay for the weekend," said Murray, who has slipped a place to world number three after his surprise fourth-round exit to Marin Cilic at Flushing Meadows last week.

That defeat still rankles with Murray, especially after he made the US Open final last year only to lose to Roger Federer and then had to watch as Juan Martin del Potro shocked the Swiss on Sunday night to claim his first grand slam title.

However, he is trying to focus on the Davis Cup and has not yet taken time out to reflect on the Cilic match.

"I've had a good season and I think I'll come back better from the US Open, I'll learn from it," he said.

"I played a bad match but I haven't sat down with my coach and discussed what I have to work on."

Murray knows he has a key part to play in this weekend's encounter against Poland.

"It is a massive match for us because we have to try to move back up through the groups," added Murray.

"In singles we should be the favourites but they have got a very good doubles team (they have a world top-10 ranked doubles pair of Marcin Matkowski and Mariusz Fyrstenberg) and we will have to play well in the doubles. We also have to get the crowd into it as much as possible."
