Context paragraphs:
West Ham United F.C. Reserves: The West Ham United Academy is recognised as one of the most successful academies in modern football, hence its nickname the Academy of Football.  The introduction of the FA's new Academy system in 1998 has placed even more emphasis on the developing of young homegrown players and today the youth system at West Ham is more important than it has ever been.  With the influx of many foreign players in the Premier League during modern times, West Ham United has been regarded as one of the few remaining clubs in top flight to continue producing and playing homegrown English players.

He represented the Croatia national team 53 times, playing at Euro 1996 and at the 1998 World Cup, when Croatia finished third.

Mark Noble: Mark James Noble (born 8 May 1987) is an English footballer who plays as a central midfielder and is captain of West Ham United.

Gary is probably best remembered by West Ham fans for being a member of the team hammered 6-0 in the League Cup Semi Final first leg at Oldham Athletic.  This proved to be his penultimate game in the famous Claret and Blue shirt.  In addition to West Ham, Gary also played for Notts County, Rotherham United, West Bromwich Albion, Hartlepool United and Lincoln City.  His greatest moment probably came in helping West Brom to promotion via the playoff final at Wembley Stadium in a team managed by Argentinian and Tottenham Hotspur legend Ossie Ardiles (1993).  In May 1985 he was to witness a nightmare when 56 spectators were killed in a horrendous stand fire while playing for Lincoln against Bradford City.
