In FIFA 18, he was definitely the best RB in FIFA. But this year he does not feel so good. He seems weaker, his tackles are not so good and he does not go in attack often. His pace feels very good and he can catch anyone and his passing and crossing is very good, too. To sumarise, I think that he is the second the best RB after Walker, but Kyle's price is very high at the moment. So buy Valencia for now and when Walker's price drop, buy him.
