9) Carlos Tevez and Javier Mascherano to West Ham
Two fine players arrived in England surrounded by plenty of controversy. Arriving in 2006, both players had left just a year later, and the controversy was because both players’ rights were owned by Media Sports Investments (MSI) rather than Corinthians, and West Ham were not only fined by the Premier League for breaching the rules governing registration but also forced to arrive at a settlement with relegated Sheffield United, who – according to Neil Warnock – went down as a direct consequence of Tevez’s form.
