"I feel that when I raise my level of the serving, I'm the one who can even take control of the match".
Winning the longest final in Queen's history - at two hours and 57 minutes - was just reward for Cilic's superb week on the lawns of Barons Court, which banked him a cheque for?413,601 ($548,764).
Asked how long he can play for, Djokovic grinned, saying: "Who said 40?"
Nadal maybe hasn't played that well in Wimbledon last couple of years up to his standards, but he's won it several times, played finals several times.
"I've played some good tennis, have played some tough opponents". I was just thinking how I can return his serve and how I can get into play and position myself well in the next point.
LONDON-Novak Djokovic celebrated his 800th career victory at Queen's Club today.
However, the spring in his step on the London grass-courts was evident as he dispatched Adrian Mannarino 7-5, 6-1 to set up a semi-final against another in-form Frenchman, Jeremy Chardy, who yesterday defeated Frances Tiafoe of the U.S. 6-4, 6-4.
Romelu Lukaku, Eden Hazard give BEL big win
Unless Panama beat England in Sunday's Group G match, Belgium will be through with a game to spare while Tunisia will be out. That goal served to halt Belgium's early dominance, but they did grab a third with nearly the last kick of the half.
He could not quite reach that level again but was still happy with his grasscourt form having lost narrowly to Roger Federer in the Stuttgart semis last week and beaten former Wimbledon champion Andy Murray for the first time at Queen's. There's a lot of grass court players.
"Last year I had a match point and couldn't convert it, this year it was Novak. I'm playing great, back again, I'm 31 on the paper, but I'm 19 in the real sense".
Despite soaring temperatures, neither player backed off in a tense deciding set, with Cilic finally earning the first break point opportunities in the eighth game.
The BBC, who were televising the semifinal match between Kyrgios and Marin Cilic, apologised for that was seen.
Following important wins over John Millman and Grigor Dimitrov before that, the former world No 1 - now down at No 22 in the rankings - is just two matches away from a morale-boosting maiden Queen's win to head into Wimbledon next month.
On this evidence against Mannarino, which followed an impressive win against Grigor Dimitrov on Thursday, Djokovic looks to be heading in the right direction and will be a contender at Wimbledon in a fortnight. But Djokovic grew in confidence, breaking back twice to take the set.
