"I brought self-confidence" - Dominik Koepfer before the start in Hamburg

Since this week, Dominik Koepfer has been number three in German men's tennis after Alexander Zverev and Jan-Lennard Struff. However, the 26-year-old has never played a tournament at ATP level in Germany. The premiere takes place today, Tuesday, in his first round match at the Hamburg European Open against the Japanese Yoshihito Nishioka.
