[1][2][3] Alegre took Boca Juniors' presidency in 1985 after winning the election to former chairman Alberto J. Armando, and succeeding interventor Federico Pollack, who had been in charge due to the deep financial crisis of the club[4] that included the closure of La Bombonera and a players strike.

Accompanied by his friend and running mate, Credico-op Bank director Carlos Heller, Alegre inherited a financially insolvent football club and a stadium unable to meet municipal safety requirements.

The iconic La Bombonera stadium had been repeatedly closed for structural failures, and lawsuits against Boca Juniors were filed almost weekly.

[6] He also announced the sale of land acquired earlier by the team in the waterfront Puerto Madero district, a move opposed by Boca's former president, Alberto Armando.

The treasurer during their last term, Pedro Pompilio, was elected president of the team following Macri's election as Mayor of Buenos Aires in 2007, and both the late Pedro Pompilio and his successor, Jorge Amor Ameal, who was also part of the Alegre's management board, continued Alegre's policy of acquiring players from less prominent teams.
