Manchester: Hooliganism is causing a "huge image problem" for European Championship co-host Poland with every round of league matches marred by crowd trouble, a UEFA executive said on Wednesday.
Ahead of the influx of football fans in the country next year, Polish authorities have vowed to adopt a zero tolerance toward hooliganism.
But the ongoing struggle to eradicate violence among Polish fans was highlighted when they clashed with police in Lithuania around a friendly on Friday. About 60 Poles were detained for throwing bottles, flares and benches at police and security guards. One guard was injured.
