A Sporting CP youth graduate, he made his professional debut in England, serving two brief loan spells first at Bristol City[2] then Oldham Athletic,[3] both in the Football League One.

In the following January transfer window he moved countries again, joining Greek side Panionios FC, initially on loan.

[8] After a short and unassuming spell back in Portugal, Lourenço moved abroad again, signing in January 2011 with UD Alzira in the Spanish Segunda División B.

He reunited at the club with former Sporting teammate Beto,[9] and both were released in June after the team's relegation, having appeared in a combined total of three games.

[12] Lourenço eventually switched allegiance to Angola, earning his only cap on 10 August 2011 by coming on as an 85th-minute substitute for Manucho in a 0–0 friendly in Liberia.
