In the 2006–07 season, Bahia continued to remain in the first team for the side at the start of the season, playing at centre–back and left–back positions. His first goal then came on 21 September 2006 against SC Veendam in the third round of the KNVB Cup, which saw Feyenoord win 3–2. However, he suffered an concussion during a match against Excelsior after colliding with Serginho Greene, that left him out for three weeks. Bahia then returned to the first team on 19 October 2006 against Basel, where he started the whole game, in a 1–1 draw. On 5 November 2006, he scored his first league goal of the season, in a 2–1 win over Vitesse. In a 3–0 loss against AS Nancy on 30 November 2006, Bahia was at fault when he scored an own goal; and eventually, Feyenoord were banned from European competition following hooliganism prior to and during the match against them. On 30 November 2006, he signed a new contract with the club, keeping him until 2009. His third goal of the season came on 28 January 2007, scoring in a 3–1 win over RKC Waalwijk. At the end of the 2006–07 season, Bahia went on to make thirty–six appearances and scoring two times in all competitions.
