Shortly after Radwańska's first-round loss at Stuttgart Open, Martina Navratilova stated that she was too busy to continue in her part-time role as Agnieszka Radwańska's consulting coach. Radwańska stated, "I just wanted to thank Martina for her time and efforts over these last few months. It was a great experience to work with one of the all-time greats. However, we both agreed that as Martina could not commit 100% to the project then it was not going to work as a long-term partnership."
