Andy Murray's work pattern with coach Amelie Mauresmo will come up for even more examination now that Wimbledon is entering its final five days but there is no doubt that their relationship is secure as he heads for the quarter-finals today against Vasek Pospisil.

Mauresmo says of their working life in The Guardian: "I like the relationship that we have. I would not have stayed around if the human part of the relationship wasn't going to be good. I would also not stay around if the results were not good or if he wasn't happy with that.

"I'm happy because he is such a hard worker. He's a great guy to work with."

In the Daily Mail, Mike Dickson writes that it would be no surprise if by the end of Wednesday, Wimbledon has its first semi-finals featuring the top four seeds in 20 years - which just shows how difficult it is to make seeding decisions ahead of The Championships.

Pospisil was born and raised in Canada, but his mother, father, and two brothers are Czech born. Pospisil will relish playing in the Wimbledon quarter-finals, which will give him one of the greatest tests of his career. 

But as renowned coach Nick Bollettieri points out in The Independent: "One problem for Pospisil is that his workload this Wimbledon has been heavy. He's played 19 sets of singles and 12 of men's doubles - that's 31 sets of tennis. Murray has played 14."

All of the coaches still involved at the sharp end of Wimbledon will know that the pressures can only mount from this point onwards.

Nobody has progressed quite as smoothly as former champion Roger Federer who now has a difficult test  to reach the semi-finals as he takes on the Frenchman Gilles Simon, the 12th seed.
