On-fire Andy Murray capable of his greatest achievement at Wimbledon 2015

A little over one year ago, Andy Murray strolled into the press conference room of the Wimbledon warm-up tournament at Queen's in London, only to be met by a barrage of manic, nonsensical questions all carrying the shameless implication that the gender of his coach could somehow negatively impact his tennis. Among several surreal scenes, the British number one was forced to calmly and in all seriousness explain that, no, Amelie Mauresmo's inability to prance around the men's locker room would not affect how he hits his forehands and backhands.

After a year of working together, the pair have killed off such sentiments forever. With his convincing triumph in Queen's, Murray arrives at Wimbledon categorically on fire. So far in 2015 he has earned a stunning 41-6 win-loss record for the year, having triumphed in 87.2% of his matches, with 20 wins in his last 21 showings.

For context, Murray's greatest winning percentage in a full season stands at 86%, his career winning percentage at 76.9%. It is clear that Murray is calmly and assuredly piecing together one of his best overall years, one of those years in which only one milestone remains.

This calmness is the most essential ingredient to his revival. Andy Murray is still Andy Murray – during the French Open, the Brit faced the erratic youngster Nick Kyrgios in the third round. Rather than worrying about tennis, the pair seemed more interested in competing to see which player could curse more frequently and the loudest. So, for two hours, loud, screeching swear words rained out of the Suzanne Lenglen stadium, almost reducing the apologising commentators to tears in the process.

The calm lies in Murray's tennis, where he has rediscovered his natural approach to the game. Under the no-nonsense aggression of Ivan Lendl, the variety in Murray's game was somewhat blunted in favour of pure efficiency. But over the past year, Murray has slowly rediscovered the variety that propelled him to the top of his game and he is using it correctly, fluidly mixing his offence and defence alongside his creative, imaginative side. Although Lendl's guidance brought tremendous success, it seems Murray is very aware that competing with Novak Djokovic in this peak of the Serb's career will require every last drop of the talent he possesses.

Such is the belief in Murray, even a difficult draw can't extinguish the flames of hope. On Friday, the Brit was moved into a questionable part of the draw that is quite difficult to predict. On paper, he may have to face Jo-Wilfried Tsonga, Rafa Nadal and Roger Federer just to reach the final. Question marks abound in this section; a section in which the biggest unknown is the most known 14-time slam champion of all.

Two weeks ago, Rafael Nadal bounced back from his French Open loss to Novak Djokovic by winning the low-level ATP 250 in Stuttgart, only to fall to Alexandr Dolgopolov in his opening match in Queen's. These three results are almost a microcosm of Nadal's woeful 2015, a year in which there have been numerous bright sparks that have suggested a revival was on the cards for the two-time Wimbledon champion, only for any hope to be snuffed out in the most brutal manner. Most shocking is how, at times, Nadal has been so unshakingly convinced that a certain result or score was a sign of his impending return to the top, rendering the subsequent crashing disappointments twice as painful.

But he is still Rafael Nadal. Murray may well have been presented with a golden opportunity to defeat the Spaniard and achieve some damage control on his 2-7 record against Nadal at slams, but while his opponent still stands and his knees remain functional, he will always carry the threat and potential to burst into form and become a force once again. Four matches until their prospective quarter-final match could be enough.

Before Nadal, however, Murray may have to reckon with the net play, power and athleticism of Tsonga. Although Tsonga is a supreme talent, it's debatable whether somebody Murray holds a 10-3 record against really counts as a difficult draw. Tsonga has largely been either injured or an irrelevant force for the past few years. Still, earlier this month, Tsonga shocked everyone by reaching the French Open semi-finals, upsetting Kei Nishikori in five sets. If that's what Tsonga can do on his worst surface, Murray will have to be prepared for what he can do on his best.

All the while, lurking ominously in the distance is the top two and last year's pair of finalists. Murray has landed in the bottom half with the second seeded Roger Federer, whose year has been very difficult to assess. His level generally hasn't appeared too far off his form in last year's great revival, but despite losing to a transcendent Stanislas Wawrinka at Roland Garros, few would argue that the first half of his slam results – a round three loss to Andreas Seppi in Melbourne and a quarter-final defeat in Paris - haven't been disappointing. Still, Federer appears to be rounding into form nicely on his native surface with an eighth win at the Halle ATP 500 a week ago, and there is every chance that he will uphold his end of the bargain with Murray to land in another semi-final.

Meanwhile, don't be fooled by the French Open final. One loss doesn't change the fact that, in the year of 2015, Novak Djokovic is the dominant force in tennis, and such dominance isn't likely to stop. He is also still strangely underrated on grass, despite the fact that last year's second Wimbledon title now places the tournament as his second most successful slam. It perhaps has something to do with his invisibility during the grass season – Djokovic hasn't contested a pre-Wimbledon grass event since 2010 – but his ability to saunter in and reach three Wimbledon finals in four outings in his first grass court event of each season only further bolsters these achievements. After his five-set defeat to Djokovic in Paris, Murray was convinced that the gap between the two 28-year-olds was closing. Whether this is truly the case remains to be seen.

It is clear that this tournament will contextualise Murray's level in his second coming more than any other single result this year. When he captured his two slams, he managed to time his ascension perfectly, peaking at the precise moment Nadal embarked on another of his knee injury hiatuses whilst Federer began his temporary steep drop in form. The Scot has no such luck this time.

If Murray wishes to win his second Wimbledon, he will likely have to pass through two, or even three of the only three active male tennis players with greater CVs than his own. It would be an incredible sporting achievement, but with his perfect preparation and his current level surely far beyond what he could have dreamed of after his final match of 2014, it is an attainable one. And if he is at all short on motivation, he should know that, if he is the last man standing on the final Sunday night of Wimbledon, the locker room would be his to invite whomever he wants into it.
