I wonder how Iran will approach this? Only joking!

They went with a nine man defence against Nigeria, with a sole isolated front man and made no attempt to attack.

Argentina went with a very defensive looking 3-5-2 in the first half against Bosnia & Herzegovina , looking much better when switching to 4-3-3 after the break, with the introduction of Gonzalo Higuain. Surely coach Alejandro Sabella did not make the formation decision just on the basis that Higuain was not ready for 90 minutes, it must have more to do with his belief that 4-3-3 leaves too much space for the better teams to exploit.
