Michel Platini warned of a return to hooliganism’s “dark days” as he was re-elected unopposed for a third term as president of Uefa.
The Frenchman says there is a rising trend of “nationalism and extremism” being observed in stadiums.
He reiterated calls for a European sports police force to avoid events witnessed in the “not-so-distant past”.
“A past where hooligans and all manner of fanatics called the shots in certain European stadiums,” he added.
Platini was a player with Juventus when crowd trouble prior to the 1985 European Cup final against Liverpool at Heysel Stadium led to the deaths of 39 people.
