How do you guys find these players like Strandberg, Drage etc?

As per the post, just how do you find these guys?

Strandberg has been immense for me, nearly an 8 average and scores goals and is very very cheap!
Yet when I scout him, he comes up as decent for Championship at best and even after a few games he is now 2.5 stars and decent for premiership (I am Southampton)

So even with better scouts I doubt I would pick him out amongst the phil jones and hummels

SO how do you do it? oh and Thanks to those that do!
