Jo Ramirez, McLaren
's former long-time team manager, has slammed fellow Mexican Sergio Perez
. McLaren ousted Perez, 24, after a single season at the end of last year in favour of Danish rookie Kevin Magnussen
"As a driver Sergio was actually not bad (at McLaren)," Ramirez, a former advisor to Perez, told motorline.cc. "I think he was also getting better. Sergio was just not good enough as a person. He didn't really cooperate with the team, he was too cocky. His attitude was very bad," he claimed.
"He was unpopular with the engineers, with everyone. I often criticise him in the media, but I do not criticise him as a driver. He's a good driver. It's such a shame," Ramirez continued. "I was at the Jerez test this year and spent time with McLaren and Sauber
, and no one was able to say something good about Sergio. They all say that he needs to change his attitude if he wants to stay in formula one." (GMM)
