- England plays Wales in Euro 2016 Thursday
- Lens, population 34,190, hosts game
- Up to 50,000 fans expected in Lens
- Town has 10,000-capacity fan zone
(CNN)It has its own Louvre museum, but the 50,000 people expected to descend on the small northern French town of Lens this week will be coming for a very different type of show.
They will be there to watch England play British rival Wales in Euro 2016 -- a game that will attract worldwide scrutiny, for what happens both on and off the pitch.
In truth, mainly off it -- England's presence at European soccer's showpiece tournament has already been accompanied by hooliganism.
Outbreaks of violence prior to its opening fixture against Russia in Marseille prompted governing body UEFA to threaten disqualification of both nations if trouble occurs in future tournament matches.
On Tuesday, Russia was handed a suspended ban from Euro 2016 -- in essence, a final warning.
The French authorities' security planning has been further complicated by Russia's game with Slovakia on Wednesday in nearby Lille -- through which England fans will travel en route to Lens.
