Alberto Zapater Arjol (born 13 June 1985) is a Spanish professional footballer who plays mainly as a defensive midfielder for Canadian Premier League club Atlético Ottawa.

He was given his official debut on Zaragoza's first game of 2004–05, against Valencia CF in the Supercopa de España: although the Aragonese ended up losing 1–0 he put up a solid performance overall, confirmed in the 3–1 second leg away win.

[8] In the following season, he helped the club to finish as runners-up in the Copa del Rey (losing the final to RCD Espanyol)[6] while also only missing three league matches; his strong tackling and the amount of fouls he committed earned him the nickname of 'The Bull', given by Diego Maradona.

[6] In late July 2009, after being instrumental in Zaragoza's return to the top division, and already playing pre-season football with the Maños, Zapater left for Genoa CFC for around €4.5 million, as the Spaniards were also immerse in a deep financial crisis.

[29] Zapater took part in the 2005 FIFA World Youth Championship, in a Spanish team that also featured future senior internationals Cesc Fàbregas, Fernando Llorente and David Silva.
