If there only was a way that you could get the expanded article...I'm not going to read Araos' stuff, but I am curious as to what he means by "stick with the 3-4-3". It didn't seem to me like we were playing a 3-4-3 last match, but moreso only had two up top. Harrison also was more of a wingback than a midfielder.
But maybe those items I pointed out were players not familiar with what they were being asked to do, and it should have taken a shape more like a 3-4-3.
