Tottenham will look to kickstart their European campaign in the Russian capital after losing 2-1 to Monaco at Wembley last time out. Russian and English fans clashed repeatedly in Marseille before and after their Euro 2016 group stage game in June. Groups of Russian fans arrived well prepared for trouble, equipped with mouth guards and martial arts gloves, and French police struggled to cope, deploying tear gas and water cannon. Russian fan leaders who were in Marseille for the June violence have been warned against a repeat performance, and Tottenham has urged its fans to keep a low profile in the Group E match."All the Russian fans who were in France, all the supporters, were summoned to police departments and hour-long conversations were had with them. No one wants to take revenge on anyone for anything," Alexander Shprygin, head of the All-Russian Fans' Union, told The Associated Press. "Everyone wants to live a quiet life and everyone forgot about the English a while ago."Two board members from Shprygin's group, which has been accused of far-right links, are currently serving prison sentences in France related to the Marseille violence. However, he said when English fans arrive in Moscow their "safety will be at a much higher level than in Marseille this summer, obviously as long as they don't provoke the citizens."While CSKA fans were not prominent in the Marseille violence, with supporters of others Moscow clubs such as Spartak and Lokomotiv playing a central role, CSKA has been repeatedly punished by UEFA in recent years for fan racism and occasional violence at games. When Manchester City visited in 2014 in the Champions League, UEFA ordered the game to be played in an empty stadium.Russian authorities swamp many football games with hundreds, even thousands of police as a matter of course, including for relatively minor league fixtures. Only around 300 Tottenham supporters are expected to travel, according to Ivan Ulanov, CSKA's head of fan outreach. In Marseille, English fans made a show of occupying the city's Old Port area, which antagonized Russian fans and French locals, but Spurs fans have been told to hide their allegiance in the Russian capital.Elsewhere, former runners-up Monaco will be looking to build on their impressive opening win over Tottenham Hotspur when they welcome Bayer Leverkusen to the Stade Louis II. One of the most highly-anticipated showdowns of the group stage sees reigning champions Real Madrid head to Germany to take on 1997 winners and 2013 runners-up Dortmund at the Signal Iduna Park. Sporting Lisbon and Legia Warsaw are expected to be fighting it out for third place and a Europa League berth in the new year and both lost their opening matches. FC Copenhagen and Club Brugge, the Group G outsiders, meet in the Danish capital with Copenhagen looking to build on a 1-1 draw away to FC Porto last time out. Leicester City get set for another historic moment as they host two-time European champions Porto in the first ever Champions League game at the King Power Stadium. Sevilla and Lyon should fight it out to go through to the last 16 along with Juventus. Dinamo Zagreb (CRO) v Juventus (ITA) Juventus did not get off to the best start as they were held to a goalless draw by Sevilla but they will be expected to get a win under their belts in Croatia against one of the weakest sides in the competition.
