Colberg was a constructive player with great stamina, but during his time in Denmark, he was most often played out of his natural position of right half-back. In the Frem team, he was overshadowed by Walther Christensen, and in the national team, Axel Pilmark was preferred. So Colberg settled into the defensive position of full back. In 1948, Colberg got his debut for the Danish national team, but he was only used sparingly. He played four international games, before he signed a professional contract and was excluded from the amateur-only national team. Hans Colberg signed for Lucchese Lucca in the Italian Serie A.Here, he came to his right as a creative playmaker in the half-back position. Colberg played three seasons in Lucchese, including the last season in the secondary Serie B division, before ending his career in 1953.
