Murray plots Sunday coup
Andy Murray is hoping his serve will prove to be the key weapon in Sunday's Davis Cup clash with Fabio Fognini in Naples.
Leading Italy 2-1 in the quarter-final, Great Britain need to win one of Sunday's reverse singles to progress to the semi-finals for the first time since 1981.
Murray will be first up against Fognini, before James Ward faces Andreas Seppi.
It is five years since Murray last faced Fognini in singles action, when the Scot was a straight-sets winner in Monte Carlo, and the world No 8 has already turned his attention to plotting another victory over the Italian.
"I'll need to serve well against him," Murray told www.daviscup.com. "He obviously plays very well from the back of the court when he is dictating the points.
"Getting free points on my serve will allow me to be aggressive on his service games. I think that's the weak part of his game. His serve is attackable, so I will need to serve well myself and put pressure on his serve by going for my returns."
Murray discovered he was dehydrated when asked to take part in a drugs test after spending 255 minutes on court on Saturday.
His recovery overnight will be crucial to Britain's chances on Sunday, with GB captain Leon Smith well aware exactly what the 26-year-old brings to the team.
"This is why we are so blessed to have Andy in the team," Smith said on www.daviscup.com.
"He's a fighter, he's a champion and you see over the last couple of days how much he brings to the team. His Davis Cup record is now pretty amazing when you look at it."
