Former Wimbledon champion Goran Ivanisevic says Andy Murray made a “big mistake” by parting ways with coach Ivan Lendl.
Murray split with Lendl in March last year and has failed to recapture his 2013 form under new coach Amelie Mauresmo.
The big-serving Croatian told the BBC that ending his partnership with Lendl was the worst thing he could have done for his tennis career.
“Last year was up and down for him, he changed the coaches. For me that’s maybe his biggest mistake, letting Ivan go,” Ivanisevic told the BBC.
“Because it was a perfect match. They did everything well together.
“They won two Grand Slams, he played the best tennis under Ivan, they were similar tennis players.”
