The 2014 tennis season ended strongly for Serbian athlete Novak Djokovic. He claimed seven titles last season including the Wimbledon title and the Barclays ATP World Tour Finals title. For the third time in his professional tennis career, Djokovic has also ended his 2014 season as World No. 1, and he is going to continue to fight for the top spot in 2015.

Speaking ahead of his first match at the 2015 Qatar ExxonMobil Open in Doha in an article on ATP's officia website, Djokovic has revealed his goals for the 2015 season. According to the 27-year-old seven-time Grand Slam champion, he is going to take exactly the right measure of himself during his participation in his current tournament and maintain a balance in his life.

Djokovic said that he has to maintain his quality performance and do as effectively as possible in every tournament that he competes in. By doing so, Djokovic believes he has a good chance of retaining the top spot in men's tennis.

Despite the fact that there is a new breed of young guns in tennis who will also fight to get to the top of the world rankings, Djokovic is looking optimistic that he will be able to perform well in 2015.

"I still want to continue on doing what I have done so far, because I have enough reason to believe that this is something that is going to, I think, allow me to have a big opportunity to stay at the top of men's game," Djokovic said. "If you want to fight for World No. 1, you need to kind of be able to play most of the big events, especially Grand Slams, and you need to be able to win at least one or two of them if you want to be No. 1."

Djokovic knows that he has to take it one step at a time. He has to carefully move from one tournament to the next if he wants to progress and achieve his goal in 2015.

Djokovic Successful In First Match In Doha

Last week, Djokovic pulled out of the final match against Andy Murray in the exhibition tournament Mubadala World Tennis Championship in Abu Dhabi due to an illness. He kicked off his 2015 season at the Qatar ExxonMobil Open and had a successful debut after beating fellow Serbian and compatriot Dusan Lajovic in straight sets, 6-2, 6-1, in less than one hour.

Djokovic had an amazing performance on break points against Lajovic, converting six out of seven break point opportunities. He will face Ukrainian Sergiy Stakhovsky in the second round on Jan. 7.
