Andy Murray warns against Davis Cup complacency

London: Andy Murray insists it is too soon for Great Britain to start dreaming of a first Davis Cup semi-final place for 34 years.

Murray joined forces with his brother Jamie to defeat Jo-Wilfried Tsonga and Nicholas Mahut 4-6, 6-3, 7-6 (7/5), 6-1 in the doubles rubber on Saturday and give Britain a 2-1 lead in their quarter-final.

The hosts need just one more victory from the two reverse singles on Sunday to guarantee a last-four showdown with Australia or Kazakhstan in September.

But Britain wasted a 2-1 advantage against Italy in last year`s quarter-finals, with Murray beaten by Fabio Fognini when the victory was within reach, so the world number three isn`t getting carried away just yet.

"Right now I`m still pumped from winning the match. But I`ve played matches where you have a massive high and adrenaline rush, then in the evening you can feel fatigued," he said.

"I lost to Fognini last year when physically I wasn`t ready to get to the level I needed after back surgery.

"I`ll deal with whatever cards I`m dealt and hopefully play a good match."

Murray admitted he was feeling sore after suffering a hip injury when he slipped in the third set.

But he is ready to play through the pain when he faces either Gilles Simon, or potentially Richard Gasquet, in the first singles on Sunday.

"It`s a bit sore. I slipped in the same place yesterday. Thankfully it`s not a muscular thing so that`s good," he said.

"The French have options but I`ve played well against both of them on the grass before so that`s a positive."Reunited on court for the first time in over two years, it was another memorable moment for the Murray brothers as they whipped the Queen`s Club crowd into a patriotic fervour with their dominant display.

"To play with your brother for your country is really special. It`s a magic day. The crowd were brilliant, the weather was great and we won," Jamie said.

"I knew if I took care of my own game we would have a chance because you expect and believe Andy will make things happen."

Andy added: "When we`ve played on the tour I want to do well for Jamie. It`s a bit different when I play with Jamie in the Davis Cup. You want to do well for the country as well."

With France on the verge of a first defeat against old rivals Britain since 1978, captain Arnaud Clement could bring in Gasquet in place of Simon to face Murray.

Gasquet was rested on Friday and Saturday as he recovered from his run to the Wimbledon semi-finals last week.

But Clement revealed the world number 13 is now ready to return to action.

"Richard is fit. He had just a few days of practice. He is ready and fit for tomorrow," he said.

"We are going to talk about it a bit later. Maybe something will change or maybe not."

Regardless of who gets the nod to face Murray, Clement acknowledged the 2014 runners-up have a big fight on their hands to avoid a last eight exit.

"It`s a real advantage for Britain now. Tomorrow is going to be a difficult day for us. We now how hard it is to beat Andy but we are going to try," he added.
