RIO DE JANEIRO, Feb. 9 (Xinhua) -- Brazilian Serie A club Atletico Mineiro sacked coach Oswaldo Oliveira on Friday after a heated exchange with a reporter in which he needed to be restrained by a club official.

Oliveira took offense to a question from Radio Inconfidencia's Leo Gomide about his tactics in a 1-1 draw with Atletico Acreano in the Copa do Brasil on Thursday.

After angrily accusing Gomide of bias, Oliveira began taking a question from another journalist before abruptly setting off in pursuit of the reporter, whom he accused of using abusive language.

The men were separated by one of Oliveira's assistants before the press conference resumed.

Atletico Mineiro president Sergio Camara denied the incident had an impact in Oliveira's sacking, saying the decision was based on the club's poor results.

"Atletico needed to play convincingly and that didn't happen," Camara said. "Our performance [on Thursday] was worrying and I have to act. Maybe with another coach we can improve."

Oliveira issued a written apology on Friday.

"As a human being under stress after a tough match, I reacted immediately to defend myself," Oliveira said. "The words that I heard made me angry. I lost control and as a consequence my reaction was irrational."

Gomide denied directing profanities towards the coach.

Oliveira, whose long coaching career has included spells at Flamengo, Corinthians, Palmeiras, Santos and

The Belo Horizonte club said assistant manager Thiago Larghi would assume the coaching position on an interim basis.
