Dynamo president Chris Canetti also sent a letter of recommendation.
"It's the first time I've ever done it," Kinnear told the Houston Chronicle. "You're recommending him to play in the English Premier League, and you're giving your reasons why and you give a brief history of your time with him and what you see are the assets and characteristic of him that would make him successful over there."
On his letter, Kinnear revealed some of the points he made.
"I said (Cameron's) overall technical ability is good, physical ability good, discipline on and off the field and game and tactical awareness on both sides of the ball, versatility (are good)," he said. "I think he's a good person off the field. And off the field he won't be a distraction at any time.
"I think he has the characteristics that will make him a successful player in the English Premier League. We talked about his inclusion into the national team, his accomplishments here - All-Star, Best XI, and (Dynamo) Defender of the Year, leading the team to the playoffs and stuff like that."
