True, yet I feel you guys don't give Batigol enough credit.
As
@Balu said (and you could tell from my immediate reaction at the time), you fixed something that wasn't broken, but it may well have won you the game.
I do have a lot of time for Batistuta, but rate Crespo higher as the pure striker "reference in the box" (same goes for the unpicked RvN).
@Raees makes a good point about how he could switch from sublime to donkey in no time, which is very much what is at the root of it all. Crespo's technique was superior, which made him more resourceful in resolving the various situations which arise in tight spaces. Batistuta was a lot more limited in that regard, and it showed, particularly when under pressure.
Watch any top 20/50 Bati or Crespo goals and you will see the difference, Bati had an insane long range shot and was a real warrior, a very determined and strong-willed player, which made him ideal for a "lesser team" and counterattacking setups. You couldn't leave him in space or he would hurt you, but give him no space and he suddenly wasn't half as dangerous.
Argies found that out themselves witnessing how the most unbeatable they looked in the 90s/00s was with Crespo, and not Batistuta. The better and more superior they were as a team, the more Crespo proved to be a better finishing touch.
With the team/setup you have, I'd argue Crespo was always the better fit.
