Andy Murray takes on former grand slam finalist Marcos Baghdatis as he hopes to make it through to the next round of Wimbledon.
The Scot goes into the round three match the only Brit left in the tournament, after 20-year-old Heather Watson was knocked out on Thursday.
Murray will also feel the heat knowing his former coach Miles Maclagan, who now coaches Cypriot Baghdatis, is in the opposite camp.
Rafael Nadal's shock Wimbledon exit may have buoyed fans' hopes, but will also serve to ramp up the pressure on the 25-year-old.
Little-known Czech Lukas Rosol caused one of the biggest upsets in tennis history on Thursday when he dumped out the two-time Wimbledon champion in the second round.
The shock result saw bookmakers slash odds on Murray to win from 10/1 to 11/2.
Maclagan, who worked with Murray between 2007 and 2010, has been coaching Baghdatis since last summer.
Of the Nadal result, he said: "It affects Andy a lot. His job will be to stay thinking about the next match. The pressure increases for him because everyone's looking to see if he's going to play (Roger) Federer or (Novak) Djokovic in the final now."
Murray said he did not think have his former coach in the opposing camp would have any bearing on the match. He received another boost on Thursday when potential opponent Milos Raonic was beaten by America's Sam Querrey.
The British number one revealed he avoids watching replays of his games, and also tries to steer clear of lucky routines, although he does avoid wearing new socks.
