Germany manager Joachim Low has praised his side's patience following their 4-2 win over Greece in the quarter-finals of Euro 2012.
Georgios Samaras cancelled out Philipp Lahm's 39th-minute opener early in the second half before goals from Sami Khedira, Miroslav Klose and Marco Reus sealed the victory for the three-time champions.
Speaking to reporters after the game, Low said: "That was a class performance from the team to reach the semi-finals for the fourth time in a row.
"We can be proud of the team, it was clear that the Greeks could make something out of nothing. We failed to take an early lead, but we did not panic.
"There were a few changes and I thought I had to change things after three wins."
Germany will now face either England or Italy in Warsaw on Thursday.
