Guillermo "Guille" Luis Franco Farquarson[2] (born 3 November 1976) is a former professional footballer who played as a striker.

Franco began his career with Argentine Primera División side San Lorenzo, playing with the team from 1996 to 2002 mainly as a right winger.

[3] On 25 September, it was disclosed that due to West Ham's perilous financial situation following former chairman Björgólfur Guðmundsson's financial collapse, West Ham's CEO Scott Duxbury, and their Sporting and Football Technical Director Gianluca Nani, had part financed the deal from their own salaries.

[citation needed] On 24 April 2010, Franco assisted Scott Parker, who scored for the winner in a 3–2 victory against Wigan Athletic; a win which would see them safe from relegation.

[9] He signed a one-year deal, and made his debut coming on as a second-half substitute for Santiago Silva in a 2–2 draw at Independiente in the first fixture of the 2011 Clausura.

Subsequently, he played the starting minutes of the Copa Libertadores debut against Caracas FC, suffering a shoulder injury that left him out for the remainder of the season.
