In early December 2011, Ricardo Sanchez was super excited to start working with Caroline Wozniacki, but the cooperation has already come to an end and all it will be remembered for is Wozniacki's failure to win her first Grand Slam title at the Australian Open and her actual fall to No.4 in the rankings following the quarterfinal loss at the tournament, after reigning the top spot for most of the time since October 2010.
The cause of the split is that the new coach couldn't find his way in the confines of the already established system of Wozniacki and her father Piotr. In simple words, Piotr had his own way of coaching and Ricardo was supposed to adapt to it, rather than to install his way of work. The two systems clashed, the outcome was that Caroline was confused and Piotr asked Ricardo to leave. (photo: © Neal Trousdale)
