I assume that you have lots of talent just waiting to be given a chance.
Having said that, whomever they turn out to be, I think they would benefit from being taught techniques to play against taller players than the average latin american 6", as Europeans tend to be more in the 6'2" to 6'4 range. This places your players at a disadvantage which, however small, can make or break a game.
In a dream world, it would also help if defenders were encouraged to develop their forward abilities - the element of surprise can work wonders. I look forward to the friendlies and 2008 qualifiers.
