One of the consensus greatest players in modern football could end up gracing the East End of London with his presence as Barcelona attacker Lionel Messi, a three-time Champions League winner, may well end up being one of the Argentine players at the Boleyn Ground as the South American giants take on Croatia in an international friendly.
Other names likely to be involved include Manchester City goalscorer Sergio Aguero and Manchester United wing wizard Angel di Maria.
Mario Mandzukic of Atletico Madrid, former Tottenham Hotspur star Luka Modric and Real Madrid recruit Ivan Rakitic could all make up the opposition for Croatia.
A statement on West Ham United's official website said: "In what is likely to be his only appearance at the Boleyn Ground, Messi and his Argentina team-mates will take on their fellow 2014 FIFA World Cup qualifiers in what promises to be a hugely entertaining clash."
The "prestige" international friendly is scheduled to take place on Wednesday, November 12.
