Djokovic will hope to avenge his defeat to Haas in the Halle final this month
World number four Novak Djokovic produced a professional display to overcome plucky Israeli Dudi Sela and reach the quarter-finals of Wimbledon.
The Serb rarely had to produce his best tennis, breaking Sela seven times on his way to a 6-2 6-4 6-1 victory.
He will now face Tommy Haas after the German 24th seed overcame Russian Igor Andreev in straight sets.
Lleyton Hewitt, meanwhile, produced a sensational come-from-behind 4-6 2-6 6-1 6-2 6-2 win over Radek Stepanek.
The Australian former Wimbledon champion rolled back the years - and overcame a leg injury - to bounce back from two sets down to steam-roller the Czech 23rd seed in the final three sets.
Highlights - Hewitt comes back from the brink
Stepanek himself summoned the trainer after the fourth set to strap up his troublesome left knee, but it was to no avail as Hewitt - cheered by a raucous bunch of Australian fans - displayed all his old spirit to win through.
"It's always tough to come back from two sets down. I had to dig deep, not look too far ahead and find a way to win," said Hewitt.
Hewitt will now face Andy Roddick, who engineered a clinical 7-6 (7-4) 6-4 6-3 win over Tomas Berdych.
The American sixth seed looked impenetrable on serve and did not yield a single break point, but Berdych was also looking in good touch.
However, the Czech, seeded 20, went down in the first set tie-break and Roddick did not look back, securing a break in each of the next two sets to reach the quarter-finals.
"It's definitely the best I've played so far," said Roddick. "I'm having so much fun. I love playing here. It's an honour and that's something that's never lost on me."
And on his last eight match against Hewitt, he added: "I think Lleyton and I have built up a healthy respect for each other over the years. We're a couple of old guys now. It's something I always look forward to."
Haas, meanwhile, the oldest player left in the men's draw, showed superb timing off both wings to wear down Russian Andreev.
He's going to put a lot of pressure on me, so I just have to be patient and wait for the chances
The 31-year-old held his nerve in a first-set tie-break, before a break of serve in each of the next two sets earned him a 7-6 (10-8) 6-4 6-4 win.
The Djokovic-Haas quarter-final match-up is a repeat of the pre-Wimbledon Halle tournament final last month, won by the German.
But Djokovic, who has a 2-1 winning record overall against Haas, will enter the match fresh after dispatching Sela in just 89 minutes.
That despite Sela, the first Israeli in the last 16 at Wimbledon for 20 years, earning two break points in game three of the first set.
Both were saved by Djokovic, though, and the Serb soon settled into his rhythm to ease through the contest and into the last eight.
And the 2008 Australian Open champion does not believe his defeat to Hass at Halle will have any bearing on their quarter-final at Wimbledon.
"(In Halle) I was still getting used to the grass and movement, the way I should play," he explained. "But here it's a different story. I've played really well the last two, three matches. Quite confidently.
"Tommy is certainly a great player, and he's playing really well lately, taking Roger Federer to five sets in the French Open, winning Halle, and then some marathon matches here.
Highlights - Easy win for unseeded Ferrero
"He's very aggressive, he plays serve and volley and goes for both serves. He's going to put a lot of pressure on me, so I just have to be patient and wait for the chances."
Djokovic is a potential semi-final opponent of Federer, who beat Roger Soderling in straight sets earlier on Monday to reach the last eight again.
However, Federer must first get past big-serving Croat Ivo Karlovic, who hit 35 aces - taking his tournament haul to 137 in four matches so far - on his way to an impressive 7-6 (7-5) 6-7 (4-7) 6-3 7-6 (11-9) victory over Spanish seventh seed Fernando Verdasco.
As expected, it was a match dominated by the serve, with Karlovic's monster delivery proving too much for Verdasco, who was unable to force a single break point.
A rain delay weighed in the Croat's favour as well, Karlovic reeling off three straight games after the break to win the third set 6-3, before defending three set points in the fourth set tie-break to win through to his first Grand Slam quarter-final.
On the other side of the draw Juan Carlos Ferrero, a potential quarter-final opponent for British number one Andy Murray, upset eighth seed Gilles Simon of France in straight sets 7-6 (7-4) 6-3 6-2.
The Spanish former world number one needed a wild card to get into this year's tournament, but has grasped the opportunity with both hands and always had too much for a lacklustre Simon.
The 29-year-old is the first wild-card entry to reach the Wimbledon quarter-finals since eventual champion Goran Ivanisevic in 2001.
