Poland took the lead through Robert Lewandowski's goal early in the first half
Poland 1-1 Greece
Poland's substitute goalkeeper Przemyslaw Tyton earned the hosts a draw in a dramatic opening match of the 2012 European Championships.
Tyton saved a penalty from Greece skipper Giorgos Karagounis after Arsenal keeper Wojciech Szczesny was sent off for bringing down Dimitris Salpingidis midway through the second half.
Poland had led 1-0 through Robert Lewandowski and Greece had Sokratis Papastathopoulos sent off for two yellow cards in four minutes at the end of a disastrous opening half.
But substitute Salpingidis equalised with his first touch after six minutes of the second half and the 2004 champions could have gone on to make it a winning start to the tournament but for Tyton's heroics.
Russia 4-1 Czech Republic
A dominant performance from Russia saw them outclass the Czech Republic to take a grip on Group A.
Arsenal winger Andrey Arshavin, who ended the season on loan at Zenit St Petersburg, had a hand in putting Russia 2-0 up, being involved in the build-up to Alan Dzagoev's side-footed opener and then setting up Roman Shirokov to score.
The Czechs got one back from a neat finish by Vaclav Pilar but Roman Pavlyuchenko set up Dzagoev for his second and then the ex-Tottenham forward completed the scoring with a fine individual effort.
