UEFA says it has concerns about safety in the eight newly built or reconstructed stadiums to be used for next year's European Championship in Poland and Ukraine.
UEFA Head of Stadium and Security Marc Timmer said that European football's ruling body is closely monitoring ongoing construction works "to make sure that all minimum standards are met."
Timmer says that "at every venue, with no exception, there have been made many changes on our request." He says this is still a major concern as "until a venue is really commissioned, you never know what's going to happen. They might make changes."
Earlier this year, UEFA ruled that Poland's Miejski stadium in Poznan, which will host three matches, could not be more than half full due to safety issues.
