Novak Djokovic is flattered to hear Andy Murray and his new coach Ivan Lendl are plotting ways to beat him at Wimbledon.
Djokovic holds all four grand slam titles and will arrive at the All England Club as top seed and the overwhelming favourite to defend his crown.

Murray, seeded second, has been his most regular challenger but Djokovic has won 13 of their last 15 meetings, including at the Australian and French Open finals this year.
The Scot will hope Lendl's reappointment can help turn the tide and has admitted that beating the world number one will form part of their Wimbledon preparations.
"It's flattering to hear that," Djokovic said.

"I know there's been a lot of talk about a potential match-up between Andy and me, and with Ivan coming to his team, but it's still very early.
"We have to be respectful to all the players at Wimbledon, more than 120 players, so we take it by step by step."
Murray reunited with Lendl earlier this month, having enjoyed the most successful spell in his career with the Czech between 2012 and 2014.
Boris Becker said he was "surprised" by Murray's decision to go back to his former coach, given the British number one's excellent recent form, but Djokovic disagreed.
"I don't think it's a surprising decision from Andy," Djokovic said.
"When Ivan was his coach Andy won a couple of grand slams, an Olympic gold medal and made the best results in his career.
"I think it was a logical move for him to take. They're a good team so it's going to be an interesting tournament."
While Murray spent last week sealing a record fifth title at Queen's, Djokovic has not played a competitive match since winning the French Open almost three weeks ago.
The Serb instead began honing his grass-court game at The Boodles on Wednesday, an exhibition event in Buckinghamshire, where he lost 6-3 7-5 to world number 11 David Goffin.
He heads to SW19 chasing a third major triumph this year, but also in high spirits after a first success at Roland Garros completed his set of grand slam titles.
"There is certainly a great sense of relief, no doubt about it," Djokovic said.
"But one thing we all learn in tennis is to reset a day or a week later. That's the sport we are in, we don't have too much time to reflect on what we have achieved.
"Of course I am very proud and thrilled to be able to hold all four grand slam titles at the same time. It's a remarkable achievement for my team and I.
"But we're moving on, it's back on grass now and starting from scratch."
As well as the calendar grand slam - winning all four major tournaments in a single year - Djokovic could still win the golden slam if he adds an Olympic gold medal to that collection.
Golfer Rory McIlroy has announced he will not be travelling to Rio because of concerns regarding the Zika virus but Djokovic has no intention to withdraw.
"No, I don't," Djokovic added. "I am still planning to go and it's going to stay that way."
