Therefore, on 14 October 1972, All Boys became Primera B champion defeating Excursionistas 1–0. He played the Primera División tournament with All Boys until 1976. In 1976, he moved to Temperley.

Managerial career
Romero embarked on his managerial career in 1981 at the lower divisions in All Boys. He had a stint as coach of Estudiantes de Buenos Aires.
In 2004, he took over as coach of All Boys with Jose Paladino. In that year, he left the institution by problems with some players and returned to it in 2007 when the team was still in Primera B Metropolitana.
On 2 April 2007, following the resignation of Nestor Ferraresi coaching for poor performance and bad football moment, Roberto Bugallo bet on Pepe Romero.
With the arrival of Aníbal Biggeri as Assistant Coach for the 2007/08 season, he manages to put together a strong team in defense and strong in attack. So much so that in the final three dates, he gets his first title as coach, defeating Atlanta 2–0.
In the 2009/10 season, his team finished fourth in the last date, defeating 2-0 Independiente Rivadavia. That way, he qualified to play for promotion to the first division, where he had to face Rosario Central. The first match, played at the Estadio Islas Malvinas, finished tied 1-1. Although everything seemed to be lost and would dispute the return visitor, Pepe Romero got his team give great blow that evening in Rosario, when All Boys defeated 3–0 at the Estadio Gigante de Arroyito, achieving promotion to the Primera División after 30 years of absence in that category.[1]
