In 2000, Biello returned to the Impact, but the Impact didn't qualify for the playoffs that season. As the Impact was no longer playing indoor soccer, Biello spent the winter of 2000–01 with the Toronto Thunderhawks in the NPSL. In 2001, Impact coach Valerio Gazzola chose Biello to be the captain of the Montreal Impact. That year, the Impact had a struggling season both on and off the field. The team missed the playoffs for the second straight year. Biello lead the team in scoring with eight goals and again was awarded the Giuseppe-Saputo Trophy.
