Former world's no.1 and six-time Grand Slam champion Novak Djokovic continued his freefall in the Race to London rankings, as his latest setback at the Dubai Duty Free Open put him at no.10 for 2014.

Djokovic bowed down to Roger Federer in the semifinal of the Dubai Open. Several weeks ago, the top-ranked Serb also fell victim at the hands of another Swiss in Stanislas Wawrinka in an epic five-set match at the Australian Open Championship.

The double Swiss casualty has certainly hurt Djokovic a lot in his bid to retain the no.1 spot in the ATP ranking, bumping him down to no.10 with just 690 tournament points around his belt.

"Nole was punished by two Swiss. In Melbourne he was defeated by a great Stanislas Wawrinka in the quarters while in Dubai he was beaten by Roger Federer. To be honest Djokovic has not been playing that bad, but apparently he can't get through tough situations like he used to do in the past," Tennis Tonic reported.

Djokovic is still at no.2 in the world ranking and has a wide margin over the up-and-coming Wawrinka. However, with the Indian Wells and Miami Masters coming up, Djokovic has to come up with a better game plan to finally put the break on his unlikely freefall.

Not Good Choice for Nole!

Ion Tiriac, former tennis player turned businessman, believed Djokovic might have made a wrong choice in hiring his former ward and Grand Slam winner Boris Becker as his coach.

"I don't know if Boris is a good coach. I don't even know if he is a coach... Maybe he is learning how to be a coach. If Boris tries to improve the technique and shots of Djokovic, he is the wrong man for the job. You cannot teach a world-class player like Djokovic more in this respect," Tiriac said in an interview, according to Tennis Tonic.

Djokovic pointed out that he hired Becker to help on the mental aspect of his game, making him strong in tough situations in Grand Slam tournaments.

"We're not significantly changing anything. The biggest thing he can contribute is the mental approach. That's one of the reasons Boris is here, because of the big matches and the Grand Slams. I felt I dropped two or three titles in the last two years I could have won," Djokovic said.
