The guys that have won Grand Slams have the ability to focus for long periods of time but Dimitrov has struggled with that.

He doesn't stick to what he does best when matches get tough and those moments against the very top guys and dangerous players like Verdasco have cost him.

He's so exciting to watch, had his best year last year and is at an age where he can still make an impact, but the field is so strong.

The first is saved. A mammoth serve from the Spaniard just when he needed it most.

The second... Djokovic takes! It's greeted with a fist pump after 50 minutes of this enduring battle.

Djokovic again the conductor, orchestrating the rally as Bautista Agut scuttles across the baseline before clipping the net with a backhand.

The Spaniard then goes long - two set points.

Deep breath from Bautista Agut, composing himself after a clawing a point back against the 12-time Grand Slam champion in another service game that looks set to go the distance.

But that Djokovic slice is just too much! Acute, precise, unreachable... he holds.

Fantastic rally.

Djokovic always in control, pulling Bautista Agut around like Geppetto. The Spaniard answered nearly everything the former world number one threw at him, but couldn't coax a well-placed Djokovic volley beyond the tape.

40-15.

Such high level tennis from both players. It is turning into a long set.

Bautista Agut is going toe to toe with Djokovic and is hanging on in here.

Bautista Agut recovers from going a break down to make an important hold.

Well, well, well... the trusty slice lets Djokovic down, after another enduring rally.

Break point saved by Bautista Agut, who looked relieved to see that one drop the other side of the net.

Nothing beats a slide on clay... and Djokovic slid into almost every point in that monster rally before a Bautista Agut forehand proved a stretch too far.

The Serb makes no mistake from the net next time round though, coaxing a volley home to earn a first break point.

Bautista Agut cracks the tape with his second serve and watches it loop into the air before dropping agonisingly outside of the box as he double faults.

Djokovic tickles over slice after slice off his backhand, before his opponent makes the error and goes long - 15-30.

There’s one place on site you’ll always find people waiting to get their balls or programmes signed. There aren’t tunnels between the courts here at Roland Garros, so players often walk through the crowds to and from their matches.

Novak scrambles back to 40-30. He's digging in, with every shot accompanied by a series of grunts and groans.

Another drawn out rally finishes with Bautista Agut finding the net, and Djokovic finding the hold.

Djokovic had controlled most of the early running, although Bautista Agut is doing his best to remind him who is the higher-ranked player here in that fifth game.

Stunning winners down either wing left the Spanish fans inside Lenglen shouting ‘Vamos Roberto!’

Djokovic applauded his racket in praise, then stepped up his game to hold.

Frustration gets the better of the Serb as Bautista Agut held to love in the following game, Djokovic remonstrating with himself as he screams and shouts at the red dirt.

The crowd respond with encouraging applause as they sense the former world number one has lost his way a little.

Djokovic came out flying, but he looks shaky now. 15-30 down on serve after a loose forehand goes adrift.

A hold to love for Bautista Agut. Clinical in that game.

Good footwork from Bautista Agut, complemented by deceiving eyes as he sends Djokovic the wrong way with a mid-court forehand.

He follows it up with a passing winner from deep...

If you haven't been to Roland Garros then I can assure you Court Suzanne Lenglen is a pleasant place to watch top-class tennis. Especially when it is not cold and damp.

The site's second show-court had a makeover before this year's tournament - new, smart wooden seats with a beige all-weather coating, plus a lick of grey paint on the steps of the steep stands.

Outside is a hive of activity after also having a spruce, fans gathering to gawp at the big screen outside, take that social media-perfect snap next to a statue of six-time French Open champion Lenglen or queue up to get into the brand-spanking new courts seven and nine.

Long from the 13th seed, who looks frustrated by his own sloppiness.

It allows Djokovic to close out.

Superb shot from the Spaniard. He's got his eye in, catching the whites of the Roland Garros lines.

Djokovic responds with his fourth ace of the match but then stumbles to deuce.
