The Dortmund forward was overjoyed at converting for die Mannschaft as they marched into the last four of the competition, and revealed that cramp hampered his celebrations.
The Dortmund man started for his nation for the first time in a major tournament and struck in the 74th minute to secure die Mannschaft's passage into the last four, after their opponents had briefly threatened to stage a comeback in an entertaining second half. Germany also recorded a record-breaking 15th consecutive victory in competitive games in the process.
Speaking to reporters after the final whistle, Reus admitted that he was overjoyed to score in such a prestigious competition.
"It was a great day in my career. It's my first time at a European Championship. I got to play from the start and it was really great. In the first three games I did not play. Then I play my first game, scoring my first goal and we win. There is almost nothing better," the 23-year-old explained.
Reus continued to talk about the motivation he received from Low as he made his Euro bow, revealing that he was expected to make a nuisance of himself among the Greece defense.
"What Joachim Low told me? I should play my way, as I always play. I want to play naughty, that is what the coach gave me for my European journey."
Still beaming, the youngster finished on a light hearted note by stating that his only regret was a relatively low-key celebration.
"My first thought after the goal? I had a cramp and could not celebrate. I wanted to celebrate with Jerome [Boateng], but that did not really happen. Now we must look to the semifinals. I still try to do my best, everything else you need to ask the coach."
Germany will meet either England or Italy on June 28 as it bids to reach a second consecutive Euro final.
