Novak Djokovic believes he is peaking at just the right time as the world No.1 prepares to step up his bid for a second Wimbledon title.

Djokovic took the express route into the fourth round on Saturday, thrashing French 28th seed Jeremy Chardy 6-3 6-2 6-2.

The Serb, who faces German 13th seed Tommy Haas for a place in the quarter-finals, played a flawless first two sets without a single unforced error and eventually hit 38 winners and served eight aces in one hour and 26 minutes of total dominance on Centre Court.

While several of Djokovic’s title rivals, including Rafael Nadal and Roger Federer, have fallen foul of the shock defeats and injury withdrawals that have rocked Wimbledon, the 26-year-old has progressed serenely into the last 16 without dropping a set.

“My results are getting better and better, so this is very encouraging going into the second week,” Djokovic said.

“I felt great from the start till the end. I had that super focus.

“I saw the stats that I won 100 per cent of first serves. That was incredible for me.

While Florian Mayer, Bobby Reynolds and Chardy have been contemptuously swatted aside by Djokovic, he acknowledges Haas is likely to provide far more resistance.

At 35, Haas is the oldest player left in the men’s draw, but he has been playing with renewed verve over the past 18 months, climbing back into the top 15 following a series of injuries.

Haas was also a Wimbledon semi-finalist in 2009 and Djokovic has no intention of underestimating the German.

“He loves playing on grass and beat Roger in the final of Halle last year,” Djokovic said.

“He doesn’t look like a 36-year-old for sure. He’s full of confidence on the court and he’s been playing very close to the best tennis of his life.

“There’s no clear favourite in that match.”

Djokovic won their last meeting, in the French Open quarter-finals in straight sets earlier this month, but he admits Haas pushed him hard enough to suggest he could do more damage on grass.

“You wouldn’t expect him to play his best at the French Open because clay is not his surface, but he did,” Djokovic said.

“He’s proven everybody wrong because he’s so fit and he moves around the court really well. He’s perfect for grass.”

Five other men are making their maiden appearance at the fourth-round stage.

France’s Kenny De Schepper, the 26-year-old world No.80, beat Argentine 22nd seed Juan Monaco 6-4 7-6 (10-8) 6-4 to book a last-16 spot at a major for the first time.

De Schepper will face experienced Fernando Verdasco after the Spanish former top 10 player, now at 54th in the world, cruised past temperamental Latvian Ernests Gulbis 6-2 6-4 6-4.

Lukasz Kubot, ranked 130, is the second Pole to reach the last 16 after 24th seed Jerzy Janowicz also booked his place on Friday.

Kubot beat 25th seed Benoit Paire 6-1 6-3 6-4 and next faces French world No.111 Adrian Mannarino, who has made the last 16 at a major for the first time in 14 attempts.

Russian 20th seed Mikhail Youzhny, a quarter-finalist in 2012, defeated Serbia’s Viktor Troicki 6-3 6-4 7-5 and goes on to face British second seed Andy Murray.

Spanish fourth seed David Ferrer, a quarter-finalist last year, managed to escape the carnage, downing Ukraine’s Alexandr Dolgopolov 6-7 (6-8) 7-6 (7-2) 2-6 6-1 6-2.

Ferrer will face Croatia’s world No.49 Ivan Dodig for a place in the quarter-finals.

Czech seventh seed Tomas Berdych, the runner-up in 2010, beat South African Kevin Anderson 3-6 6-3 6-4 7-5 and takes on unseeded Australian Bernard Tomic, a quarter-finalist in 2011 who put out French ninth seed Richard Gasquet 7-6 (9-7) 5-7 7-5 7-6 (7-5).

Dodig reached his first fourth round at Wimbledon when Dutchman Igor Sijsling quit trailing 6-0 6-1 1-0, taking the record number of withdrawals to 13.

Italian 23rd seed Andreas Seppi beat Japan’s Kei Nishikori, 3-6 6-2 6-7 (4-7) 6-1 6-4, also for a maiden last-16 place.

Seppi will face Argentine eighth seed Juan Martin Del Potro, who defeated Slovenia’s Grega Zemlja 7-5 7-6 (7-3) 6-0.
