Rafael Nadal's shock Wimbledon exit has piled even more pressure on Andy Murray's shoulders and now the Scot's former coach Miles Maclagan is plotting his downfall.
Little-known Czech Lukas Rosol caused one of the biggest upsets in tennis history when he dumped out the two-time Wimbledon champion in the second round.
Nadal has beaten Murray three times at the All England Club, including in successive semi-finals, and the pair were seeded to meet again in the last four this year.
Maclagan, who worked with Murray between 2007 and 2010, will be more than just an interested spectator on Saturday when the Scot faces Cypriot Marcos Baghdatis in the third round.
Maclagan has been coaching Baghdatis since last summer, and he is hoping Rosol's Centre Court heroics have made the all-conquering top four a little jittery.
Speaking about his man's hopes against Murray, former Great Britain Davis Cup player Maclagan said: "He has a chance, it's definitely slim.
"Andy's a heavy favourite. But what happened last night has probably made a lot of guys in the locker room sit up.
"The top guys will be thinking, 'Wow, we can be beaten', and the players think, 'We can beat the top guys'. You claw every bit of hope you can. Even a match that's not that even, the percentages are still quite small often."
Although Murray will not want to start looking too far ahead, Maclagan thinks the result will have made a big impression on the fourth seed.
"It affects Andy a lot," Maclagan, 37, said. "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.
"People who aren't so into tennis forget there are other good players out there. But I'm sure he's paid a fair bit of attention to that result."
Murray received another boost on Friday when rising star Milos Raonic, a potential fourth-round opponent, was beaten by America's Sam Querrey, but the fourth seed is still likely to have to get past the likes of Marin Cilic, Juan Martin Del Potro and Jo-Wilfried Tsonga to make the final.
Murray and Baghdatis have split their six meetings with three wins each and have faced each other twice since Maclagan moved into his current role, with Murray winning both times.
Discussing the situation of Baghdatis having Maclagan on his side, Murray said: "When I played him last year in Tokyo it was a little bit weird having Miles there.
"But I played him again in Brisbane and felt much more comfortable. Now I wouldn't have thought it would have any bearing on the match really."
Maclagan agreed with his former charge, saying: "It's past the awkward stage. It's been two years now, it's a long time. Marcos has played him twice, and metaphorically and literally we're in different boxes now."
Maclagan shared some friendly banter with Murray's team as they finished their respective practice sessions, with the Scot again hitting with British teenager Oli Golding.
The relationship is respectful rather than particularly close, with Maclagan saying: "The tour's a small place so we see each other all the time. I still get on well with the guys.
"We never really had that relationship where we would talk on the phone all the time. We got on well but unfortunately for me there was a big age gap so we weren't round each other's house playing Playstation.
"I spent two and a half years with him so I have a huge amount of respect for the work that he does. I think it's very unappreciated."
After parting ways with Maclagan, Murray worked with a number of coaches on an ad-hoc basis before hiring Ivan Lendl at the end of last year to form one of the game's most high-profile partnerships.
Their association began well when Murray produced one of his best grand slam performances to fall just short of beating Djokovic at the Australian Open, but since then the gap to the top three appears to have widened.
Maclagan added: "I think in tennis in general it's not always about the specific knowledge, it's about the weight that comes with it. I hope, having been in his corner, that what I know about Andy carries that extra edge.
"The same as what Ivan Lendl has to say might be the same things I was telling him but it carries a lot of weight because he's got eight grand slams in his trophy cabinet."
As well as a comfortable victory, Murray, 25, will also hope to avoid the controversy of his win over Ivo Karlovic, who made serious accusations about the integrity of the tournament.
The Croatian alleged the court officials were biased towards the home favourite in a series of foot fault calls, but it is understood Karlovic will not face any sanction for his comments.(reopens) Murray is looking no further than his next match, so declared Nadal's defeat was far from his thoughts.
Murray told BBC Sport: "It's one of those things where it's completely irrelevant to me unless I reach the semi-finals.
"The draw has opened up for, say, Philipp Kohlschreiber who was playing Nadal in the next round, not me.
"I've got a tough opponent in Baghdatis and maybe tomorrow he has a performance like Rosol."
