Czech Republic boss Michal Bilek has blasted fans for booing striker Milan Baros.
Two early goals from Petr Jiracek and Vaclav Pilar earned Bilek's men a vital 2-1 win over Greece in Euro 2012's Group A last night.
However, despite their team's success, the Czech Republic supporters repeatedly whistled when Baros was in possession.
"The fans were excellent and I am grateful for their support but I am really sorry that they still whistle at Milan Baros," said Bilek.
"Baros has scored 41 goals for the national side and he doesn't deserve it.
"The fans made a great atmosphere and rooted for us but the whistling is unnecessary as it is a team sport and the other players are also upset by it. They can feel it and they are sorry as they are a team and Milan Baros is one of them and doesn't deserve the whistling."
The Czechs will qualify for the quarter-finals of a major tournament for the first time since 2004 if they beat Poland in Wroclaw on Saturday.
