Hi there,
I've bought a very expensive player recently, he cost 4.3 mil$ which is 3 times more than casual players in my league level. He is 5* and has 37 points which is still a long run to 6*. The point is that he is not training 3 times faster than other players, maybe 2 times at max, moreover his performance from the matches are 7-7-6-6-6, so not impressing at all.
Would you sell him ?
