Marlins manager Ozzie Guillen is brushing off criticism from reliever Heath Bell.

Speaking on Tuesday about the team's latest ordeal, Guillen said Bell is entitled to his opinion. But the manager added that he has received about 30 supportive messages from current players and those he managed with the Chicago White Sox from 2004-2011.

Guillen indicated that Bell has not fully accepted blame for his struggles this year.

Bell, who signed a three-year, $27 million contract with Miami to leave San Diego as a free agent last winter, lost his job as the Marlins' closer after posting an 8.47 ERA in his first 21 appearances.

During a radio interview Monday with Miami station WQAM, Bell said the Marlins need a manager "that everybody respects and looks up to."
