Born in Tegucigalpa, Distrito Central, Francisco Morazán, López joined Olimpia's youth system at the age of 7. He remained in the youth ranks until 2010, where he was finally able to make the breakthrough into the first team.
Olimpia
On 8 August 2010, López made his league debut against Hispano F.C., coming on for Bani Lozano in the 70th minute. He scored his first goal – which was the second of the match – to help seal a 2–0 victory.[1]
Following the 2012 Summer Olympics, López was continuously linked with a move to Europe, with English side Wigan Athletic being an alleged suitor for the young playmaker.[2][3] However, these transfer links came to nothing, and López remained at Olimpia for the following season. In 2022, a British journalist called Kieran Morris claimed that Wigan's interest in the player, which was reported as fact in national newspapers in the UK and Honduras, had been fabricated by him and his friends, who contacted various press outlets pretending to be a club insider or journalist as a prank.[4]
On 18 January 2016, López returned to Olimpia and signed a six-month contract after it was confirmed that he would no longer continue with Houston Dynamo.[10] He made his first appearance since his return the following 31 January in a 0–0 draw against Real España, replacing Romell Quioto in the 56th minute.[11] He would help Olimpia win the 2016 Clausura tournament, which was also the club's 30th title win.[12]
Al-Khaleej
López signed a two-year deal with Saudi Professional League side Khaleej FC on 28 June 2016. He made his debut the following 12 August in the 3–1 defeat against Al-Faisaly, scoring his first goal.[13] On 22 January 2017, the club announced through their social networks that they had terminated the contract of López.
On 13 January 2018, López signed for Costa Rican side Liga Deportiva Alajuelense.[16] He made his league debut for the club in a 3–1 loss against Pérez Zeledón.[17] López would score his first goal in the return fixture against Pérez Zeledón in a 3–0 win.[18]
