The Russians, coached by veteran Dutchman Dick Advocaat, are in buoyant mood ahead of the Euro 2012 kick-off after a morale-boosting friendly victory last Friday.
Advocaat's side produced a vibrant attacking display to thump an out-of-sorts Italy 3-0 in Zurich leading expectations to flower in some quarters.
Russia were one of the revelations of Euro 2008 with their delightful attacking flair-filled play under the guidance of another Dutchman, Guus Hiddink, destroying Holland in the quarter-finals before losing in the semi-finals.
However, Advocaat is keen to quell the rising tide of optimism.
Although his side produced some fine attacking play in Zurich, with Zenit St Petersburg strike pairing Aleksandr Kerzhakov and Roman Shirokov particularly impressive, ably supported by Andrey Arshavin - on loan at Zenit from Arsenal - Advocaat is more concerned about his defence.
In truth, they allowed Italy several clear chances but some poor finishing was the main reason the Azzurri failed to score.
"One friendly victory, even if it was a thrashing of Italy, doesn't make us the Euro favourites," said 64-year-old Advocaat, who is stepping down after the finals to take over Dutch side PSV Eindhoven.
"We should remain realists, it was just a warm-up game.
"It's good that we scored three goals against Italy to boost our team's self-confidence but we still need to improve our defence to avoid serious problems in the group matches with the Czechs, Poland and Greece."
One man that Advocaat will be hoping repeats his form of 2008 is striker Roman Pavlyuchenko, and the Lokomotiv Moscow hitman says that a win against the Czechs is crucial.
The 30-year-old - who ended an inconsistent four year spell at Premier League side Spurs in January with a transfer back home - said that it would not be an easy task to beat the Euro 2004 semi-finalists.
"We should win on Friday at any costs," said Pavlyuchenko, who was one of their stars in 2008 scoring three goals.
"We face a tough task to reach the Euro knockout stage. To achieve this goal we must win. Of course it will be tough as every European team now knows how to play quality football. But we must win this clash anyway."
While the Russians are trying to improve their defence, the Czechs have had quite a different problem to overcome in their preparations.
Before arriving at their base here in Wroclaw, traces of the potentially-deadly Legionella bacteria were found in their hotel, which needed to call in a disinfection company before Polish health inspectors gave it the all clear.
Their other major concern was over the fitness of captain Tomas Rosicky, although he resumed full training on Monday following a calf problem.
Arsenal's Rosicky, alongside fellow veterans Peter Cech of Chelsea and Galatasaray's Milan Baros, will form the backbone of the Czech challenge.
However, this side, which finished second in a qualifying group containing world champions Spain, is a far cry from the glorious 1996 team which reached the Euro final or indeed the eyecatching one that reached the Euro 2004 semi-finals.
The Czechs only narrowly edged out Scotland for second place in their qualifying group, although they did complete home and away victories against Montenegro in the play-offs.
Their friendly form since then has been patchy, though, having beaten Israel 2-1 they went down by the same score at home to a youthful Hungary side.
