Argentina World Cup stars Carlos Tevez and Javier Mascherano show up at West Ham on the last day of the transfer window and join the club in mysterious circumstances. Mascherano is unable to break into the West Ham team ahead of Hayden Mullins and moves to Liverpool in January, where he plays in a Champions League final in May, becomes an integral part of a world class midfield and eventually leaves for Barcelona three years later, becoming one of the world's most decorated centre backs. Tevez fails to score for West Ham until March, after which he goes on a run of goalscoring form which saves West Ham from relegation, culminating with the winning goal in a 1-0 victory over champions Manchester United at Old Trafford. Relegation rival clubs attempt to sue West Ham as Tevez was never officially eligible to play for the club. During the summer, Tevez transfers to Manchester United and goes on to win a Premier League and Champions League double in his debut season, followed by another Premier League title a year later. He then joins rivals Manchester City and captains the team to an FA Cup win. The following season, he is disciplined by the club for refusing to be subsitituted on by Manager Roberto Mancini in a Champions League match at Bayern Munich. Tevez then refuses to play for the club for five months, instead returning to Argentina and playing golf. He is eventually reinstated to the squad in time to overcome an eight point deficit to United and win the league on goal difference in stoppage time of the final game of the season. He celebrates this by displaying a banner with the message "RIP Fergie". Tevez goes on to play for Juventus, before rejoining Boca Juniors. However, he becomes the world's highest paid footballer when he joins Shanghai Shenua in the Chinese Super League, where he remains for a just a year, failing to impress in China and scoring only four goals. He then returns to Boca again and is a substitute in Boca's Copa Libertadores final loss to River Plate held at Madrid's Estadio Santiago Bernabéu.
