Murray and Lendl announced their decision on the British player's blog on Wednesday...
"Working with Andy over the last two years has been a fantastic experience for me," Lendl said. "He is a first class guy. Having helped him achieve his goal of winning major titles, I feel like it is time for me to concentrate on some of my own projects moving forward including playing more events around the world which I am really enjoying.
"I will always be in Andy's corner and wish him nothing but great success as he too goes into a new phase of his career."
Lendl has recently played exhibitions in Kansas City, Oklahoma City, Nashville, Charlotte and London. He has also been giving clinics in the Canary Islands as well as opening new courts in Bluffton, South Carolina, at the Ivan Lendl Junior Tennis Academy.
Murray will be defending his Miami title next week before leading Britain in the quarterfinals of the Davis Cup next month against Italy.http://news.yahoo.com/murray-lendl-end-coaching-relationship-122847303--spt.html;_ylt=A0LEVy6CtilT9XAAftBXNyoA;_ylu=X3oDMTB0dm9kMmw4BHNlYwNzYwRjb2xvA2JmMQR2dGlkA1ZJUDM2NV8x
