In October 2006, Esteban signed a four-year contract with Stade Rennais FC, worth approximately 7 million Swiss Franc, effective as of January of the following year. He became the fourth Swiss to join the French outfit, after Christophe Ohrel and Marco Grassi and Alexander Frei (who also played for Servette before Rennes, which also eventually led to some comparisons between the pair, due to their goalscoring prowess).
