Novak Djokovic has been training with Marian Vajda but the two do not appear to have any official coaching agreement, according to a statement from Djokovic's team.
Video has shown Vajda on court during Djokovic's recent hitting session at the Pepe Imaz Academy in Marbella, Spain.
"Marian came to help Novak," Djokovic's PR was quoted as saying by Novosti. “At the moment, there is no agreement on further co-operation, nor has any length for their current work been discussed further."
It added that "Vajda's role" was to "support Djokovic in training and preparations for the clay-court season."
Djokovic returned at the beginning of the season from elbow problems and reached the third round of the Australian Open. The Serb then underwent elbow surgery and has not won a match since. He recently split with both his coaches, Andre Agassi and Radek Stepanek.
Highlights from Djokovic's loss to Paire in Miami:
Vajda had been Djokovic's longtime coach before the former No. 1 got rid of his entire team around a year ago.
Djokovic is scheduled to play next week's Monte Carlo Masters, where he is entered for both singles and doubles.
