FIFA President Sepp Blatter says most allegations of match-fixing raised by Europol this week were previously dealt with.
Blatter says "most of the matches which they put in this tray, 600 or 800, have already been analyzed, dealt with and even were at court."
At Europol's briefing in the Netherlands, the police liaison agency said it knew of 380 suspicious matches played in Europe in recent years and 300 more worldwide, including national team matches under FIFA's jurisdiction.
Blatter also told reporters that countries should change their laws to help soccer prosecute match-fixing cases.
Blatter says fixing for illegal betting scams is "pure delinquency" and "we're fighting that."
The FIFA leader visited Mauritania on a tour of African countries before attending the Cup of Nations final in Johannesburg on Sunday.
