2. Nicolas MedinaArgentinos Juniors. The side responsible for producing all-time legends of the game such as Diego Maradona, Juan Roman Riquelme, and Julio Arca. Following the success of the latter's £3.5 million switch to Sunderland, Peter Reid replicated the transfer fee and went back to Argentinos Juniors for Nicolas Medina. "A complete midfield player," Reid declared. Medina was one of Sunderland's most expensive signings of all-time when he joined in 2001. But he simply wasn't given a chance in the team. He made one appearance for Sunderland during a cup tie with Bolton and the BBC even noted it as an 'impressive debut' for the Argentine. Peter Reid left the club without ever clearing up the Medina mess, and the useless Howard Wilkinson's reluctance to play the midfielder resulted in him being quoted as saying: "The evidence suggests that Nicolas hasn't got it because the previous manager didn't pick him." Well played, Howard... In 2004, a whole three seasons after signing, Medina left on a free transfer with that solitary cameo against Bolton his only appearance.
