You are not allowed to mention that "Baby Fed" nickname any more. Coach Roger Rasheed has put a stop to that sort of comparison, thinking that Grigor Dimitrov needs to be his own man.

It seems to be a tactic that is working. But there is something reminiscent of the Swiss big cheese in the way that Dimitrov has made an entrance in his first Grand Slam semi. A hold to love whips by in a flash.

Might that have been a missed opportunity for Grigor Dimitrov? It doesn't look like there is any meat on the bone for the Bulgarian as Novak Djokovic ramps up to a 40-0 lead, but Dimitrov punches down the line to take a point. 40-15.

Dimitrov has a play on a makeable volley in the next rally. He chooses to hold the stroke though, hoping the ball is heading long over his shoulder. He's wrong.

Game Djoko.

Maria Sharapova is in place to see her boyfriend treading the Centre Court boards, inscrutable behind a pair of large shades in the players' box. She will be pleased by that as an opening act. A hold to 15 and Dimitrov hops off to swap ends.

A final towel down, a rummage about in the racquet bag and we are ready to go. Grigor Dimitrov is off his stool and ready to serve.

Bigger goals like becoming the first Bulgarian to make a Grand Slam final presumably.

But will Grigor Dimitrov achieve that slice of national history? You can vote on which men will contest Sunday's final on the right-hand side of this page. No need for a stubby pencil, a curtained booth and a musty town hall though.

It is just a click away...

Grigor Dimitrov: "It was a good feeling to have a win like that against Andy Murray. I live for those moments and I have done the work and I am happily rewarded but I don't want to end things now because I have bigger goals and bigger potential."

Jimmy Connors
Two-time Wimbledon singles champion on BBC TV

"Grigor Dimitrov needs to have the confidence he ended the day with on Wednesday.

"If he starts slow and lets Novak get on top, that won't be good for him.

"Getting to the semis, you can feel the finish line and knowing winning Wimbledon is just a grasp away. It gets your heart pounding."

"It is important for Grigor Dimitrov to get off to a good start. This will be the biggest match of his tennis career, but I do think Novak Djokovic will have too much for him."

Boris Becker, three-time Wimbledon champion and Novak Djokovic's coach on BBC TV: "Novak is in good form and he is excited to be here. It's a special place to play tennis, it's always a privilege to be on Centre Court especially at the later stages of the competition.

"Dimitrov had a phenomenal match against Murray, he won the tournament at Queens and he hasn't lost a match on grass yet and is in good form but it is a 50/50 match."

John Lloyd
Former British number one on BBC TV

"Novak Djokovic he has been Mr Consistency for so many reasons but he hasn't had too much luck in finals recently. I think that's why Boris has come in, especially here, on what was his surface.

"If Grigor Dimitrov plays like he did against Murray then we could have a great match on our hands, but I do think Novak has just a little bit too much experience for him."

Ten days of baseline scrabbling and shuttling has taken its toll on Centre Court. There are some patches at the back of the court as bare as a Waca wicket.

The team of ground staff have been out all this morning ensuring that the bounce is still true though. We are just a few short minutes away from the arrival of the men who will test it out.

Grigor Dimitrov and Novak Djokovic are waiting in the wings.

"Grigor Dimitrov needs to make a good start again today and has to impose his game on Novak Djokovic. They are both great defenders but Dimitrov has to take his chances to move forward and dominate."

So how do Laura Robson's temporary colleagues in the press see today's semi-finals?

"Djokovic and Federer might well end up playing the final on Sunday. But the wider point stands; it would only be delaying the inevitable," writes the Daily Telegraph's Jonathan Liew in anticipation of a new generation., external

Simon Cambers in the Guardian, external underlines the importance of today's match to Roger Federer writing that it may well be his "best chance to become the first man to win eight Wimbledon titles".

At Wimbledon 2013, Laura Robson became the first British woman to reach the fourth round for 15 years. Twelve months on and she has stuck around well into the second week.

Unfortunately for her it has been in the media centre working as a pundit for the BBC while she recovers from a wrist injury.

So what is it like on the other side of the ropes? A bit more strawberries and cream, a few less smashes and drills according to her column on the BBC Sport website.

Richard Krajicek has applied the Centre Court know-how that brought him the men's single title in 1996 to today's matches.

He is backing Milos Raonic to cause an upset against Roger Federer, but believes that Novak Djokovic's serve might be harder for Grigor Dimitrov to get stuck into.
