The ICC's anti-corruption unit are currently working on between 40 and 50 cases as their attempts to clean up the sport continues
Several World Cup players were approached during the tournament by fixers attempting to convince influence the outing of future franchise T20 events.
The ICC were rigorous in their preparations for the tournament, briefing every player from each country and providing them with names and faces of individuals under scrutiny
Those provisions ensured that players were alert to possible threats and were in a position to actively report approaches.
"We got very good feedback because we showed players pictures of current corruptors," ICC anti-corruption unit chairman Alex Marshall told The Daily Telegraph.
"That then led to several reports from people playing in World Cup about contact they had from those corruptors about T20 events in the future.
"None of them related to approaches to fix in the World Cup. At this point as far as I know it looks as though the World Cup was clean."
Marshall, whose unit banned Bangladesh allrounder Shakib Al Hasan until October 2020 last year, says between 40 and 50 cases remain ongoing.
And after a dozen individuals - including former Sri Lanka captain Sanath Jayasuriya - were chaged in 2019, Marshall is expecting that number to rise in the New Year.
