Overrated:
Doria, Balanta, Tin Jedvaj, Kurt Zouma (these four defenders have yet to be truly proven in RL, but already can fit into 1st team of any major team in game immediately and becoming a GOD to relatively easy to achieve total best defense n minimal goals let in)
Luis Suarez(omg, looks so plain and simple....but he still performs outstandingly with those meager looking stats)
Memphis Depay, James Ward-Prowse, Will Hughes, Gabriel Barbosa, Sebastian Driussi, Aleksander Mitrovic, Alberto Cerri (these few youngsters easily grow to GODLIKE status if placed in 1st team immediately. Not truly proven in RL but easily can outshine any superstar)
Antonio Valencia, Eric Lamela, Christian Eriksen (geezz... they can easily achieve GODLIKE status in game)
Underrated: Messi & CR7 (if controlled by AI, because if controlled by AI, they never get more than 30 goals but still win the Ballon d'Or.... however, if somehow a player managed to buy them and use them, they easily can become GODLIKE but never come close to RL scoring 40-50 goals)
Marco Reus, Thomas Muller (wow, compared to Ozil, these two looks like ****)
Overall, it bores down to the match engine and tactics use. Stats itself doesnt prove anything. Well, it is just a game afterall. How real life like can it be? Too many unknown factors that influence the game as well as real life. But mostly, its as close as it could be in overall. (except for those random godlike youngsters which r unproven... geezz... in my own online community game, i always buy those youngster but get told off saying how come those youngsters is GODLIKE.... to the extend i do feel it is abit offsided)
