Born in Salamanca, Castile and León, Alonso studied civil engineering at the Polytechnic School of Zamora. After Real Zaragoza expressed desire to sign him for its youth system, he eventually started playing with local UD Salamanca in 2004, appearing in only one Segunda División game in his first season, which ended in relegation; he became a regular in the following years.
Alonso joined Hércules CF on a two-year contract in June 2009, being the first player signed by the club during the off-season. In July of the following year, however, he moved to fellow league side Real Valladolid after agreeing to a three-year deal.

However, with his playing time getting limited, Alonso terminated his contract in August 2012. He signed for Racing de Santander the following month.
After suffering relegation from the second level, Alonso joined Segunda División B's CD Leganés for one year. He left in December 2013, moving to the Israeli Premier League with Bnei Sakhnin FC.
In early January 2015, news circulated that third tier club CD Guijuelo was looking to hire Alonso. He started training on the 9th, and played his first match 16 days later in a 0–1 home loss to SD Compostela.
In November 2015, Alonso joined a host of compatriots at Indian Super League franchise Atlético de Kolkata as a replacement for the injured Javi Lara. After being an unusued substitute in the match against Chennaiyin FC, he made his debut in a 4–0 win over FC Goa, replacing fellow Spaniard Jaime Gavilán for the last 12 minutes.
