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 Primeira Liga debut on 15 August in a 2–1 away success over U.D. Leiria where he again came from the bench. On 23 December 2011 he renewed his contract 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.
