Andy Murray has urged Heather Watson to rise to the occasion when she faces Wimbledon top seed Serena Williams on Centre Court on Friday afternoon.
Watson will meet Williams for a place in the fourth round of the Championships knowing victory over the formidable American - already considered an all-time great of the game - would provide the highlight of her career.
Murray believes that a fearless approach will best serve his fellow Briton, but cautions that it will take something special to cause an upset.
"It's probably the biggest test in tennis right now. I saw a little bit of Serena's match on Wednesday, she looked extremely motivated from the beginning," Murray said.
"In some of the matches at the French Open, it didn't appear that way. I don't know if that was nerves or anything, but she looked pretty fired up the other day.
"So it's going to be an extremely difficult match for Heather but she's going to have the crowd with her.
"She has to try to use that to her advantage, try not to be intimidated and just go out there and give it a go.
"She needs to really go for it, try not to let Serena dictate, and hopefully she can serve well. That will make a big difference."
Watson, ranked 59th in the world, has never reached round four at the All England Club before but the 23-year-old is in no doubt she can topple the all-conquering American.
"Do I believe I can beat her? Absolutely,'' Watson said.
"There's no point even going out there if you don't believe you can win, because then there is no way I could possibly win anyway.
"I have to believe I can win from the first moment, from now. I'll have to be very aggressive and push myself out of my comfort zone against her."
