He started his professional career with Barcelona, without much success, and went on to amass La Liga totals of 169 matches and eight goals in representation of six other clubs.

[5] after featuring regularly in both clubs' promotion from the Segunda División, he saw very little time the following campaigns; in between, he spent 2003–04 with Real Murcia also in the top division.

[14] On 27 December 2015 he was named Real Zaragoza manager[15] but, after failing to reach the play-off positions with a 6–2 loss at already relegated UE Llagostera in the last matchday of the season, he resigned.

[18] Carreras was hired by a foreign club for the first time in December 2018, when Japan's Sagan Tosu named him as manager for the upcoming season; they had recently secured the high-profile transfer of his former Atlético teammate Fernando Torres.
