Little did anybody anticipate that West Ham's play-off final victory against Preston in 2005 would provide the launch pad for one of their most successful seasons ever, with the club securing a top-half Premiership finish and qualifying for Europe thanks to its first FA Cup final appearance in 26 years. Indeed, the thrilling 3-3 draw with Liverpool will be remembered as one of the most dramatic finals of all time.With a keenly anticipated UEFA Cup campaign and the shock arrival of Argentina World Cup stars Carlos Tevez and Javier Mascherano, the future could hardly have seemed brighter.
