Andy Murray is one of the favourites to clinch the last grand slam of the year -- US Open -- but in order to achieve this feat, he has to be on top of his game and beat top players such as Roger Federer and Novak Djokovic. 

After winning his maiden grand slam title through the 2012 US Open, the Scot has not been able to progress beyond the quarter-final stage of the competition in the last two editions. Though Murray might have reached the last four in all the grand slams so far this year, the Scot's best result has been a runner up finish in the Australian Open.

If things go well for the third seed in the upcoming US Open, Andy Murray will meet Roger Federer in the semi-finals, which is expected to be a humdinger of a contest.

Roger Federer has been in great form as he won the Cincinnati Masters defeating world number one Djokovic in the finals.

Former Tennis star, John McEnroe fails to understand why Murray does not go at the net against the likes of Federer and Djokovic.

Murray loves playing from the baseline, but he needs to come to the net and show some variety in his game to turn the heat against world class players. 

"You have to understand that, ultimately, Federer and Djokovic are better players. Murray is a great player; but for reasons I don't quite understand, he is not willing to go to net in the key moments like Federer or Djokovic," ESPN quoted McEnroe as saying.

In order to win big grand slam titles, Murray even hired Amelie Mauresmo as his coach, but with the Frenchwoman pregnant, the Scot had to opt for the services of Jonas Bjorkman to strengthen his support staff. Murray has even hired sports psychologists.

"I'm surprised that, given how much pride Murray puts into preparation, he hasn't figured this out already. He's hired everyone under the sun to coach him and even hired [sports] psychologists. If you don't send the message that you're coming to net, opponents know they can get back into the point pretty easily," added McEnroe.
