Leon Smith is Andy Murray's first coach and the Great Britain Davis Cup captain.

Here, the Glaswegian breaks down the key points of the Scot's Roland Garros semi-final with Novak Djokovic:

"The key for Andy is to serve aggressively while also making sure he keeps his first serve percentage up. That is not an easy balance. He needs to go after service winners and set up his forehand without giving Novak Djokovic too many looks at his second serve. He has to be aggressive and hit his spots. He would want to be above 60% first serve percentage for sure and making sure he is on top of the next ball, so he can dictate the point.

"That will allow him to try to stay on top of as many rallies as possible. Because it is important that he wins, or loses, points on his own terms. That is what he did in the US Open final in 2012 and the 2013 Wimbledon final and also for long spells in the Melbourne final this year also. Against the world's top player you also know you are going to take your share of the burden but you always know Andy will do that regardless.

"The bottom line is that Andy is going to have to play a great match. These are the two best players in the world this year - and both of them are aware it is an opportunity to reach a slam final and give themselves a great opportunity of winning the French Open. It is huge for them. People say Novak Djokovic is invincible, but he is human and I think he will feel the weight of expectation in this one. I think it will be brutal, there will be a lot of heart and legs involved, and that is why they are the best two players in the world. It should be an absolute blockbuster.

"It is fairly obvious that Novak goes in as favourite. No one can dispute that - it is fair, on ranking, record, form, the matches he has won the last few years. But there is obviously something in Andy's make-up which matches up well with Novak. He has had some success against him, and even when he has lost to him, there have been spells where he has been on top - he has had chances in matches even when Novak has been playing his best tennis. He has got to keep reminding himself of that. He will at some stage have opportunities in the match because of the quality that he brings."
