Thanks @H_G , but like I was saying, i am referring to Edit Mode. When i am editing the team there are no form arrows so all players will be according to their stats.
I havent worked out the Overall score, like you said it could be that.
Here is the comparison.
Both also have 1on1 Stopper skill.
What is the consistency total for them both out of interest?
Also it would be interesting to see if you swapped their played id's over and see if the same thing happens.
Looking at PES5 guide and the keeper's essential stats (DEF, BAL, RES, GK) Loris still comes out on top 356 total to 348 and even with beneficial stats added although it gets closer he still has a total of 383 to 381. So I could certainly see why with form arrows the AI could drop him but as you say in the edit screen, why?
The only stat on the essential stats that Loris loses out on by a bit is BAL 83-91. Might be interesting to make them both 83 and see if it still happens.
On a side note @Ciais made a brilliant find in PES5/WE9 and made a kitserver add on where you can alter the form arrows. I've always thought the up/down arrows are too high a % adjustment and make the Ai change the team way too much. So with that you can make a diagonal arrow the highest/lowest awarded by the AI - or whatever you like.
