Novak Djokovic stayed on course to win a ninth grand slam title by beating Marin Cilic on Centre Court to reach the Wimbledon semi-finals.
The imperious Novak Djokovic cruised into another Wimbledon semi-final by beating Marin Cilic in straight sets on Wednesday.
World number one Djokovic produced a masterclass on Centre Court to win 6-4 6-4 6-4 and stay on course to retain his title at the All England Club.
Cilic had no answer to the outstanding top seed, who looks determined to put the disappointment of losing the French Open final to Stan Wawrinka behind him and claim a ninth grand slam title.
US Open champion Cilic is still yet to reach the last four at SW19, while Djokovic can now look forward to facing Wawrinka or Richard Gasquet on Friday.
Djokovic apologised after appearing to shout at a ball girl during his fourth-round victory over Kevin Anderson on Tuesday, but had no reason to lose his cool as he dominated Cilic.
He did not face a solitary break point and made just 12 unforced errors in a clinical display against the ninth seed from Croatia.
Djokovic had to come from two sets down to beat Anderson in a match which spanned two days and looked intent on avoiding another marathon contest as he claimed an early break, taking a 2-1 lead with a volley after rushing into the net.
He then came up with back-to-back forehand winners before sending down a thumping ace to stretch his advantage to 3-1 and made Cilic work for the hold in the following game, taking a 30-15 lead before the giant Croat won three points in a row.
Djokovic had the opportunity to serve for the set and, although Cilic hung in there by saving three set points - one of which when he charged towards the net to end a captivating rally with a winner - he netted on the fourth to fall behind.
The Australian Open champion had a chance to earn a break point in the fifth game of the second set, but his backhand let him down at 30-30 and Cilic held.
Cilic was struggling to contain Djokovic, though, and the Serb came up with the break to lead 5-4 when he raced into a 40-0 lead then won his second break point when his opponent sent a forehand into the net.
Djokovic was clearly in a hurry to seal his place in the last four as he served out the set when Cilic this time netted a forehand from the baseline.
There was no halting Djokovic's momentum as he broke to lead 4-3 in what turned out to be the final set, with Cilic made to pay for a miscue from the baseline.
He then earned three match points on serve and won the second when Cilic got too much on a forehand and was put out of his misery.
