Right Masha has nothing to lose; she can try a new coach for important tournaments. 
I mean she needs someone who knows exactly what to do during a final and what preparation she needs for a Grand Slam.
Masha's victories are in her hands.
For example at the last final:
Masha’s frustration started to show—a sharp bang of the court with her racket as she fired one more in a growing tally of errors—but her solution was to hit the ball even harder. Sometimes it worked, but often it did not.
I would like to say that Miami tournament for Masha was not totally bad, she defeated many strong tennis players who had strong coaches But I think that Masha has not enough endurance to win a final. When you have not enough endurance, you becomes nervous easily and you make plenty of mistakes or you can't control yourself because you want the match to end quickly.
Everybody has noticed that Masha made plenty of unforced errors at the last final. Many fans told me that it seemed that Masha was not playing against an opponent but she was playing against herself, because only her errors caused her defeat. 
An advice of a good friend:
Navratilova said. ___________________________________________________________________ She is right. And her coach had to realize it and react. But nothing happens. They let things flow but it flows in the wrong way. Maria is not good enough physically, she has not enough endurance, she has to get more skills, move better ( she is too lazy to move, she must get moved), avoid those DF and unforced errors and upgrade her net activity which is like non existent. A good coach had to realize this since a year ago, but nothing happened as we saw in all the tournaments she played. It's too bad that now she looses to everybody. ( not only to big ones ).
IT IS AN ADVICE FOR ROLAND GARROS AND THE OLYMPIC GAMES IN LONDON 2012 !!!!
