Alan Dzagoev scored a goal in each half as Russia produced a masterclass of attacking football to beat the Czech Republic 4-1 in their European Championship Group A opener on Friday, AP reported. Dzagoev and Roman Shirokov gave Russia a 2-0 halftime lead before Vaclav Pilar hit back in the 52nd minute to give the Czechs brief hope of a comeback. Dzagoev replied with his second, in the 80th minute, and substitute Roman Pavlyuchenko added a fourth in the 82nd. Russia, a surprise semifinalist four years ago, showed it has the potential to go even further in Poland and Ukraine. If Euro 2012's opening 1-1 draw between Poland and Greece had more drama than quality, the second group match was a feast of fluent, attacking football.
