Hi just saw two players, 18 years old, 3 stars same position and no SA.

One was valued at 1.02 million and one somewhere between 100-200k, I bought the more expansive one and trained him on 'Hard' and he gained 33 points on stretching.

My lvl is 2 and I have no upgrades in my facilities.

I was hoping I bought a fast trainer, but not sure. Did I? If not, why so big difference in value?
