Authorities in Warsaw have been working hard behind the scenes to ease concerns over a planned march by Russian fans through the city to the national stadium.
Minister of Sport Joanna Mucha has played down outrage at the plan from some in Warsaw for whom that is too reminiscent of Russia's dominance of Poland during the communist era.
"I do not think there will be any problems with this march or with this day. I am sure everything will go all right," she told Reuters television.
"It is absolutely normal for the fans supporting the teams just to have a march during the tournament, so this is an absolutely normal situation."
Russian fans were also at the centre of a handful of incidents in the southern city of Wroclaw around Friday's game against the Czech Republic and are expected to be in Warsaw in force on Tuesday.
Their team produced the performance of the tournament to crush the Czechs 4-1 in an exuberant display of swift movement and flawless finishing on Friday.
That reinforced their status as firm favourites for Group A, although the Poles showed enough in a dominant first-half display against Greece to suggest they will not be pushovers.
"The Russians are favourites but we've played with teams who are better than they are. There is no reason to be scared. We are at home," Polish attacking midfielder Adrian Mierzejewski told reporters on Sunday.
"For us as players, it doesn't really matter who we play but for the fans of course there is a bit of a clash, a bit more tension in this game."
Mierzejewski and Kamil Gronicki both sounded cautiously optimistic of their chances of playing, adding to speculation that at least one of them could start.
Franciszek Smuda, widely regarded as a conservative coach who tends to stick with the same line up if he can, said he would not make more than one change to his outfield starting side.
Goalkeeper Przemyslaw Tyton, who rescued the Poles on Friday by saving a penalty with his first touch of the ball, will start in place of the suspended Wojciech Szczesny.
THREW FIREWORKS
The Russian football federation and the national team on Sunday urged their fans in Poland to behave after some supporters threw fireworks and displayed illicit banners during the game against the Czechs.
UEFA is investigating those incidents and the circumstances around an attack by around 30 fans on stewards after the match.
Coach Dick Advocaat is expected to make no changes to a squad being tipped to repeat or better their drive to the semi-finals four years ago. The two sides last played just before that in 2007, drawing 2-2 in a friendly in Moscow.
"We all know what a match against the Russians means," Poland's Grosicki said on Sunday.
"It is one of those games - against Russia or Germany - where, speaking colloquially, you have to leave your guts on the pitch."
