Andy was always the nearly man of tennis, happy to reach the finals and beat the seeds behind him but always struggling against the likes of Djokovic, Federer and Nadal etc. So what really has changed since then, well nothing except a few changes of personel behind doors but really it's just a steady improvement by the Scottish ace. It's frustrating being British and supporting Andy because he has the ability to make it to the top and the conditioning to support this but the way he loses his cool on the court is always at the back of the mind. He has already shown he can compete with the best of the best in tennis.
All the best players have the raw talent from a young age in any sport you look at Messi, Dan Carter, Rory Mcilroy all players that had to develop in their own sports from a young age and improved with experience and age. It's something which Murray will have to adapt himself too, It's a common stat. One thing is for sure his progress is exciting to watch particularly with him having time on his side.
