Poland skipper Jakub Blaszczykowski expressed his delight following his side's 1-1 draw with Russia on Tuesday.
The 26-year-old scored an explosive equaliser during the Euro 2012 Group A encounter, and he praised Poland's resolve.
"When you score an equaliser like that, it gives really good energy to the team. Smuda got his tactics spot on, and we followed them through on the pitch," Blaszczykowski told Uefa.com.
"We're still in contention, and if we win our final game [against the Czech Republic] we're through. We'll fight until the end. We've proved we can play a good game and achieve good results.
"The supporters can make a difference and we must believe in ourselves. If we have the attitude and get energy from the fans we can show them that we deserve their support."
Poland face Czech Republic on Saturday.
