If anyone knows how to stop Argentina maestro Lionel Messi, it may just be Iran coach Carlos Queiroz.
He has been credited with devising the tactics and defensive system that shut down Messi in both legs of the 2008 Champions League semifinals while Queiroz was assistant manager at Manchester United, which beat Barcelona 1-0 on aggregate. Now, he will attempt the same feat when Iran takes on Argentina in Group F on Saturday at Mineirao Stadium in Belo Horizonte.
He said Friday that "we will try to do it. But Messi is surrounded by different players now. They know each other well."
