Montoya has lost 6 kilos and a half, more or less 14.3 pounds in just a month and a half.
An ex-soldier from the British Royal Marines Regiment is now Juan's new shadow. His name is Gerry Convey and he's at McLaren since February 2003. This research came after seeing the colombian with noticeable characterisitics on his face and cheeks at the final tests in Jerez.
The change is not strange. Ron Dennis, an obssesive person about the profesionalism and image of his drivers, told the man from Bogota "You should lose 15.4 pounds (7 kilos) before you get in the car in Australia".
His weight is now about 163 pounds (74 kilos), while at the brazilian GP he was about 180 pounds (82 kilos), which is his ideal weight while he's racing.
This is going to be even harder for Montoya, since Convey is going to be Juan Pablo's new neighbor in Monaco, from January and on.
