After the short spell at Universitatea Cluj, in July 2009 he signed a contract with Oțelul Galați. In the first season under his command, the team finished eighth. The next season, Oțelul started the season with four wins in the first six games and climbed on top of the championship. They finished first the Autumn part of the season, and what seemed to be only a flash in the pan, became one of the biggest surprises in the Romanian football. Oțelul maintained its position throughout the Spring season and became Romanian champion for the first time in their history. Munteanu was seen as the primary factor for this success.
