Uefa will not open an investigation at this stage into Lyon’s 7-1 Champions League win over Dinamo Zagreb after their own Betting Fraud Detection System did not detect any irregular betting patterns surrounding the match.

Lyon have backed the decision of the French online gaming authority (ARJEL) to run checks on bets placed on the result, which in combination with Ajax’s 3-0 defeat to Real Madrid was enough to take the French club into the last 16.

Uefa have yet to receive reports from the match referee or match delegate but say at this stage they have not seen anything which warrants further investigation.

A statement from Uefa read: “We have . . . implemented a Betting Fraud Detections System as a tool against match-fixing – a system which monitors 29,000 games a season including all Uefa matches, and utilises data from more than 400 betting companies.

“For the time being this system has not shown any irregular betting patterns around yesterday’s games.”
