1. Have you tested him with TW: 93-96 (off course, AI vs AI test)?
I have tested him with TW: 96, 95 and 93, and he almost never dribbles. He just gets the ball and passes. I'm no expert on Cueto, but I do know that he was great dribbler, and that, in some situations, he preferred to dribble, escape from his markers and then pass the ball. When you assign him such value >90, he almost never dribbles. Like he don't know how to do it :/.
And if you think that I'm trying to underrate him or something, check the discussion in Pele's thread. You can only blame Konami for making Team Work to function in such weird way.
Apparently Konami made high TW values function only with pure passers/playmakers, but not with players that combine passing/playmaking with dribbling (that's why Maradona has only TW: 80).
2. Yes, but have you watched complete games of Cueto? I have, and he was human, and although he was magnificent long passer, he did make mistakes when passing. I'm not saying he doesn't deserve LPA: 96 (I really can't remember how many mistakes he made in those games I've watched, I wish I watched it more carefully), I'm just saying that since there are games of Peru (from that Era) to be found, why wouldn't we choose to believe our own eyes? And have you try to compare him to any other great long passer that you watched? For example, how do you compare him to players like Deyna (LPA: 91), Zico (LPA: 92), Didi (LPA: 93), Maradona (LPA: 93), Platini (LPA: 97) (or any other great long passer you're familiar with)?
3. Again, if you've watched his games, I want to hear your opinion about his DA (because I found almost every text, there is on the internet, about him). If we can see it for ourselves, we shouldn't rely too much on the texts (although we must rely on them, when we don't have videos).
P.S. You've actually never stated that you've watched his games, so I'm assuming that you write your comments based on his highlight videos and texts.
If you have watched full games of Cueto, you should mention that, because it means much more then text sources.
