Fulham sign Argentine teenager Tiago Casasola

Fulham have signed 19-year-old defender Tiago Casasola from Boca Juniors on a three-year deal with the option of a further 12 months, according to reports.

The Argentina Under-20 international moves to Craven Cottage for an undisclosed fee, and Fulham manager Felix Magath believes that they have signed a player with huge potential.

"He is a great talent and a player who can develop to play at Premier League and Champions League level," Magath is quoted as saying by BBC Sport.

Casasola was not named in the squad to face Derby County this afternoon.
