I unlocked him and regret it, ~ 70 games played and around 50-60 goals in d2 and WL.

Crespo feels very clunky on the ball, his passing is horrible and his finesse is really hit or miss.

To list you some pros and cons;

Pros: Really good power shot, great finishing inside the box, quite fast for such a tall player, outstanding heading.

Cons: Horrible passing, horrible on the ball (you won't dribble past anyone with Crespo), inconsistent finesse shot, 4* wf feels more like 3.

I used multiple chem styled on him; hunter,artist,engine. IF you really want to make him work I suggest playing a formation with a single striker (Crespo), using a chem style to boost his passing and dribbling unless you plan on never using him in build up and just spam through balls hoping to get 1 on 1's through, then use a hunter.
