In August 2009 Ferreira moved to neighbouring G.D. Tourizense – who acted as Académica's farm team – until the end of the season. A year later he signed for second division club S.C. Covilhã in the same predicament, and played his first match as a professional on 26 September 2010, coming on as a second-half substitute in a 1–0 home win against S.C. Freamunde.
In June 2011 Ferreira returned to Académica, and made his top level debut on 15 August, again coming from the bench in a 2–1 away success over U.D. Leiria. On 23 December 2011 he renewed his link with the Students, running until 2015.
On 12 June 2013 Académica agreed a deal for Ferreira with La Liga side Málaga CF, with the player signing a three-year contract. On 12 January of the following year he first appeared in the Spanish league, replacing injured Weligton in the 34th minute of a 0–1 loss at Levante UD.
