Trejo was born in Santiago del Estero. A product of Boca Juniors' youth system,[2] he only played once for its first team but, in the game against Club Almagro, he scored in a 3–2 away loss after a mere minutes on the pitch – the match was suspended after 63 minutes.[3]
In late December 2006, Trejo was bought by RCD Mallorca in Spain, still having not signed his first professional contract; Boca sustained otherwise and the case was taken to FIFA, which ultimately decided for the Balearic Islands club.[4] He made his first appearance in La Liga on 8 April 2007, against Getafe CF: having come on as a 90th-minute substitute, he managed to find the net for a final 2–0 home victory.[5]
On 15 August 2010, a similar move ensued, with Trejo joining Rayo Vallecano in the same tier.[9][10] He returned to the top flight in the 2011–12 season,[11] scoring four goals from 33 appearances for Sporting de Gijón but suffering relegation.[12]
In the summer of 2012, Premier League's West Ham United made an attempt to buy Trejo, but the deal fell apart.[13] One year later he eventually left Spain, going on to spend several years in the French Ligue 1 with Toulouse FC after agreeing to a four-year contract.[14]
Trejo returned to Rayo on 21 June 2017 as director of footballDavid Cobeño's first signing, six years after leaving.[15] He scored a career-high 12 goals in his first year, combining with Raúl de Tomás for 36 as the club returned to the top division as champions.[16]
