Can Novak Djokovic win all four Grand Slam titles this year?

World number one Novak Djokovic heads into the European clay court season in ominous form after his victory over Andy Murray in the final of the Miami Open on Sunday.

Djokovic looks in such command of his game and his opponents that there is already the feeling he could enjoy a similar year to his remarkable 2011, where he won 41 straight matches and claimed three of the Grand Slam titles.

The Serb, who won at both Indian Wells and the Australian Open, was asked after Sunday's victory if he felt that kind of streak was on the horizon. While he was careful not to make bold predictions, his response revealed his confidence.

"I hope so, but it's just the beginning. I don't want to predict anything. I don't want to put some additional unnecessary pressure on myself," he said.

"There is already a lot of expectations of course. Everywhere I go I have to deal with it."

But he is enjoying the moment.

"I could not ask for a better start of the season, winning three big titles," he said. "Hopefully I'm able to use this for the clay court coming up. That's extremely important for me obviously leading up to French Open."

Certainly Murray, who has now lost his last seven encounters with Djokovic, sees little weakness in his rival's game.

"He serves well, he runs well, he moves exceptionally well. Physically he's in great shape; he hits the ball well off both sides," the Scot said.

"So, yeah, he does most things on the tennis court well. That's why he's the number one player in the world."

Djokovic will be 28 next month and knows that he needs to take full advantage of his current form to add to his tally of eight Grand Slam tournament wins - five in Australia, two at Wimbledon and the 2011 US Open.

"I'm trying to enjoy the moment and also utilise this time of my career where I'm probably playing the tennis of my life and I'm feeling confident and physically fit," he said.

"I am aware that this cannot go forever. There is going to be eventually a change of generations, some players that are going to start playing better and be stronger.

"But until that time comes, I'm going to try to stay as long as I can on the top and fight for biggest titles."

Rafael Nadal and Roger Federer have career Grand Slams to their name, but winning all four of the sport's biggest events in one year remains a feat of mind-boggling proportions. Don Budge did it in 1938 while Rod Laver snared all four in 1962 and 1969 - he has a court named after him in Melbourne to mark his contribution - but neither of those two men had to compete with Djokovic, Nadal, Federer or Murray, four of the greatest figures to pick up a racket who have somehow been thrown together to snarl across the net at each other in his golden era of tennis.

Nadal intimated that the season feat was impossible when he lifted the US Open two years ago. "To win all four Grand Slams in one year I think today is impossible for anyone. That`s my feeling," Djokovic could be the one man who could prove such a prediction wrong. He was one short in 2011, but at the peak of his powers in 2015, Djoker could easily go one better this year.

Djokovic is a 27/4 shot to win all four. Expect those odds to tumble if he succeeds on clay at the French Open. In fact, he would probably be disappointed if he does the hard part in France only to come up short in the UK or the US. Nadal and Djokovic are rated as 3/2 joint favourites for the French Open. Despite his record of winning nine out of the past 10 titles at Roland Garros, Nadal is far from a certainty to continue his dominance this year.

Rafael Nadal admitted that his confidence had been shot to pieces after suffering a surprise defeat to Fernando Verdasco in the third round in Miami. A good time, then, for the Spaniard to get back on his favourite surface of clay in Monaco when the Monte Carlo Masters begins a week tomorrow. Nadal is the biggest road block one would argue in Djokovic's bid to win all four Slams in one season. Roger Federer overcame Djokovic in the last four at Roland Garros four years ago when the Serbian won the three other Grand Slams on offer and he is weaker on the clay than hard courts or grass. Much will depend on the condition of Nadal, but if Djokovic can somehow lift his first French Open title, he will have completed his collection of career Slams. It would be a tough ask for anyone to halt him winning the lot in one season with Wimbledon and the US Open likely to fall to the world number one unless injury hits or he is afflicted by a drop in his remarkable levels of consistency.
