Born in
Alcalá de Henares,
Community of Madrid, Alfaro made his professional debuts with the club at which he finished his football formation,
Atlético Madrid. He played rarely for the
Colchoneros' first team, with 18 of his 24 appearances coming in the
1992–93 season, and was also loaned to
Real Valladolid during his stint in the
Spanish capital. Alfaro signed for
Hércules CF in 1994, scoring 20
Segunda División goals in his first two seasons combined, including 12 in the
1995–96 campaign en route to a
La Liga return after a ten-year absence for the
Alicante side. In
the following year he netted a career-best 15 goals, but they were immediately relegated back. In
1998–99, Alfaro produced another solid season in the top flight, now with
Villarreal CF (35 games and 12 goals), but suffered another relegation. After years battling with chronic
tendinitis he decided to retire from football in December 2002, aged 31; his last club was Hércules, now in
Segunda División B. ==Coaching career==
