Poland striker Robert Lewandowski admits Germany are favourites to win Euro 2016 but insists he will do his utmost to dent their hopes when the sides meet on Thursday.
The Bayern Munich striker arrived at the tournament on the back of a stellar season with the Bundesliga champions after scoring 42 goals in all competitions for Pep Guardiola's side.
Poland have beaten Germany just once in 20 meetings, in a Euro 2016 qualifier in Warsaw in October 2014 with goals from Arkadiusz Milik and Sebastian Mila.
But after beating Northern Ireland 1-0 in their opening match Lewandowski, who scored 13 goals during the qualifying campaign, is keen to inflict further pain on Joachim Low's side.
"For me, Germany are the favourites for the whole tournament, but anything can happen. We have to stay calm and be confident against them," said the 27-year-old.
"No fear, no stress, but we also need to have some fun against them."
Lewandowski will come up against some familiar faces in the Group C showdown at the Stade de France, with team-mates Jerome Boateng and Manuel Neuer certain starters for the world champions.
"They know me very well, but we all know each other well," he added.
Meanwhile, Sevilla midfielder Grzegorz Krychowiak says Poland will be going all out for victory to secure their passage to the knockout stages following their opening win over Northern Ireland.
"Will we try to get just one point? No way," he said. "Such an attitude would mean a lack of respect to ourselves and to our fans. We only go for three points."
Arsenal keeper Wojciech Szczesny remains doubtful for the game after sitting out Tuesday's training session due to an injury picked up against Northern Ireland.
