Fernando Verdasco says he is feeling more relaxed than he has ever been as he prepares to face Andy Murray in the Wimbledon quarter-finals.
The 29-year-old Spaniard, ranked 54th in the world, is in the last eight of a grand slam for the first time in almost three years after suffering a severe slump in form.
Since beating Murray in the fourth round of the Australian Open and reaching the ATP finals in 2009, Verdasco has struggled to make an impact.
But since the appointment of Ricardo Sanchez as his new coach he has been growing in confidence and is cherishing the opportunity to face Murray on centre court at SW19.
"This year in general I have done well," said Verdasco. "I've not done that well in the big tournaments, but I'm here now in the quarter-finals of Wimbledon. I have a mentality that's different to what I had before.
"I feel more relaxed than ever and that helps. It's a tranquility that I'm responding to well.
"The last two years haven't been good for me and my ranking shows that. It has gone down a lot and I lost a lot of confidence every time I lost in the first round.
"I started questioning myself, I started asking why I couldn't find the form that I had before, but I started training well the week before Madrid, and really since Madrid the feeling has been different for me. I have felt much better.
"In Rome I only lost to (David) Ferrer and in Paris I lost to (Janko) Tipsarevic in five sets so the feelings I have now are the ones I have had in the last five months, they are the best feelings I have had in my career."
