[5] Toni was part of the legendary Jimmy Hagan-led sides that won back-to-back domestic leagues from 1971–1973, losing only one match in 60; to this feat, he contributed three goals from 50 appearances.

[8] Toni earned 32 caps for Portugal, his debut coming on 12 October 1969 in a 1–0 away loss against Romania for the 1970 FIFA World Cup qualifiers.

[10] One year after retiring, Toni began working as assistant at Benfica, successively holding the position under Sven-Göran Eriksson,[11] Pál Csernai, John Mortimore and Ebbe Skovdahl.

He was promoted to head coach early into the 1987–88 season, and led the team to the second place in the league and the final of the European Cup, lost to PSV Eindhoven on penalties.

He won the UEFA Intertoto Cup with the former, but was sacked due to poor results in the domestic front; with the latter, he arrived at the Ramón Sánchez Pizjuán Stadium alongside player Emílio Peixe, being relieved of his duties on 15 October 1995 following a 0–3 home loss against RCD Espanyol.

Toni returned to Saudi Arabia in summer 2010, reaching the semi-finals of the AFC Champions League with Ittihad FC.
