Forgot to say that if you are really looking for some young player so Lukaku, Babacar or Paloschi are also great players.
Lukaku and Babacar will be great in about 2 or more years but Paloschi, beside a hot prospect, he is really good for starting eleven.
I personally have good experience, in premier leuage, with Neymar and Kadlec but they are young and can flop. Lukaku was for exampel awful on my LFC game. Buy Dzeko for guaranteed result.
I signed yaya sanogo, babarcar and neymar first seaon. In second season start neymar AM babacar and yaya upfront for there age there doing well, scoring a fair few for a pair of 18 year olds
