 After his loan spell at Sparta, Tiendalli was indeed used more often by Feyenoord, but could not make the expected breakthrough he wanted on his return.In "De Klassieker" against Ajax, which Feyenoord lost 2–0, he was sent off in the match for a second bookable offence, and was also sent off in the last game of the season, a 3–2 loss against Roda JC.At the start of the 2009–10 season, Tiendalli left Feyenoord after having his contract terminated.
