An Everton fan has told ITV News the French police attack on the team's supporters in Lille was unprovoked.
Ellie Taylor said there was nothing malicious from the Everton side before officers fired rubber bullets and tear gas in the city's main square.
Any trouble has now died down ahead of the 6pm Europa League match.
But Ellie said some of her friends suffered stinging eyes and could not see properly from the tear gas.
Greg O'Keeffe, the Liverpool Echo's Everton correspondent, is on the ground in Lille and has tweeted that police have fired rubber bullets at Toffee fans.
Images appeared on Twitter of Everton supporters having congregated en masse at Lille's Grand Place square, and of the French police then arriving and gas having been set off, with the crowd dispersing.
Everton have tweeted to ask their fans to stay away from Lille city centre amid reports that police have released tear gas.

Everton striker Steven Naismith is to donate tickets to the club's matches to unemployed people across Liverpool throughout this season.
The 27-year-old Scotsman, who has already been involved in a number of charitable causes, said he hoped the "small gesture" would "bring some joy to many people".
I come from Ayrshire in the West of Scotland and spent a lot of my life in Glasgow - a city that, at times, has suffered from high unemployment.
Liverpool has a similar history and I am aware that, through no fault of their own, there are many unemployed in Liverpool trying hard to find a job and may not be able to afford a ticket.
The tickets will be made available through JobCentres around the city each week at Naismith's request, selecting people "who are unemployed through no fault of their own, are trying hard to find employment and who would enjoy watching a Premier League football match."
