When Andy Murray became one of the highest-profile male stars to appoint a female coach, it was hoped that Amelie Mauresmo would certainly spice up the Briton's game and add a new aspect of his play to dominate the sport.
Roll forward the clocks to the end of the grass court season, and it appears the smiles and laughs between the pair at Wimbledon, while probably genuine, weren't aiding any progress with the racquet.
The defending champion reverted to the traditional heartbreak trend set before him by British sportspeople by failing when expected to go for glory.
A crushing loss to trendy up-comer Grigor Dimitrov in the quarter-finals leaves Murray at something of an unnerving career crossroads. Changes will be sought - he stands on the brink of slipping out the world's top ten - but where to improve and how to flourish aren't easy questions to answer.
2014 hasn't been great for the British no.1. Injury at the tail-end of last year hasn't helped matters, but ample time has been spent on rehabilitation and that can no-longer be the sob story for the 27-year-old.
You cannot help but look upon the split with former coach Ivan Lendl as the chink in the pipe that is preventing gushing success.
Reasons are reasons and maybe we'll never truly know the exact cause of the separation - much like a seemingly lovestruck couple - but both seemed like they needed a change and that must be respected.
The long awaited appointment of Mauresmo was supposed to help Murray to swell the contents of his Grand Slam collection, which Lendl had started off with US Open and SW19 triumphs. However, when you look at the Frenchwomen's qualifications for the role, you'll find it a struggle to see the justification.
Murray claimed Mauresmo would help massage the mental side of his game. Lest we forget, though, the 35-year-old was once the world no.1 having not won a single major.
She only managed two Grand Slam victories in her career, a total considerably lacking when you look at her talent. Mauresmo was the one that clearly had a crisis of confidence, she is in no position to help anybody else.
What Murray needed was a coach - it doesn't make a shadow of difference whether it was male or female - who won major upon major and had noted experience of helping others achieve their goals. John McEnroe was a loud darkhorse for the vacant role, yet maybe his claim to the position should have been considered a little more thoroughly.
The world no.10 may well stick with Mauresmo as he aims to repeat his Flushing Meadows win in the autumn, despite claims of unrest, but it's clear they need to sit down and really work with each other.
However the breakdown at Queen's and Wimbledon clearly leaves a chasm which will probably be too big to bridge.
