A football midfielder from Argentina, Diego Alberto Galvan began playing professional football with Club Atletico Lanus in 2000. After one season, Galvan enjoyed a short stint with Mexican club Morelia, before returning to Lanus. After one more season with Lanus, Galvan moved to Portugal to join Beira-Mar, but returned to Argentina to play for Olimpo in the same season itself. Olimpo was relegated at the end of the 2004-05 season, following which Galvan was picked up by Argentine giants, River Plate. But Galvan was not able to make the most of this opportunity, and was loaned out to Estudiantes in 2006.
The midfielder found his true form with Estudiantes, and went on to bag his first title, the Apertura 2006. Due to certain conditions of the loan, Estudiantes had to shell out US $100,000 to get Galvan to play against River Plate in that tournament.
But before the 2007-08 season began, Galvan returned to River Plate, but was not assigned as starter for most of the season. He even had some very public disputes with coach Daniel Passarella. Finally in July 2007, when Estudiantes wanted Galvan back, he left River Plate for good and moved to his current club.
Later in the same month, while playing against Libertad, a Paraguayan team, Galvan sustained a knee injury and was ruled out for the next seven months, resuming play in early 2008. Due to the fact that Estudiantes fields two teams, one for the local championships and another for the Copa Libertadores, Galvan had plenty of opportunity to recover and work on his form. He has now been cleared for the full 70 minute game, which Galvan himself claims to be prepared for.
