This is not specifically related to Jose, and I hope this is not a trend he continues and he sticks with the team he has.
This is known as the South American dance of the coaches among the players and Chucho's former coach Horacio De La Peña has made some comments.

De La Peña again attacks Argentinian players
The coach of the Chilean Fernando Gonzalez doesn´t understand why so many Argentinian players change coach so often. Coria Calleri Chela and Zabaleta are at the top the list.
In statements made to the cable program "Tennis Sports". De La Peña says "so many coach changes are not well regarded. In Europe they really can´t understand these attitudes.
Argentine players are not well considered in Europe because of these those changes. The statistics show that, for example, for Guillermo Coria, Spanish Jose Higueras will be coach number 8, Calleri with 9 Zaba and Chela with 7 coaches".
Gastón Gaudio and David Nalbandian have had less coaching changes. The former champion of Roland Garros had six and the present number one of Argentina, four.
De La Peña says "Beyond the attitude of the players, the coaches must earn themselves respect, I have a yearly renewable contract with Fernando Gonzalez and we both take care of ourselves and respect each other"
