Impressive player, set of stats look somewhat outdated for current PES. I have only seen a handful of matches of Marlos so I'm a bit hesitant with suggesting exact numbers and am interested to hear other peoples findings of him. First of all defence stats should be seriously lowered to high 40's - low 50's. Marlos is hardly involved in any defensive plays and I think these stats fitted with older versions of PES. TEC and DA and Body Control could do with a serious upgrade, whilst speed stats should go down. Marlos is a nimble dribbler with a very good technique and close ball control, quick on his feet but by no means a fast player over distance. TS should be high 70's or up to 80 (78-80), ACC can be a bit higher (84-85), DA should be high 80's (86-88), TEC should be high 80's (86-90) and Body Control mid 80's I think (84-87).
Video below shows some of his first touches (I don't want to promote video's of highlights as this can be very flawed but this does show his technical abilities quite well)https://www.youtube.com/watch?v=EbSkfR7q668
