I got his champions league card after using his normal card out of one of the champions league upgrades and decided to test him out. Overall he can be good in moments and bad in others. His reaction saves are very good, he is very athletic and agile. He never catches the ball of corners and always will choose to punch the ball out which goes wrong a lot of the time as it usually ends up in the other team having another shot. He still gets beaten from OP angles as you would expect. Tea Stegan has the trait sweeper keeper which personally i don't like as most chipped through balls over the defence he comes rushing out for sometimes he has passed it straight to the other time giving them an open goal to shoot at and other times the game lets you take over but you never know if it will auto clear or you control. Other than that he overall makes good saves in 1on1's he has saved me many times saving it with his flailing arm.
Good Reaction Saves
Good 1on1 saves
Good distribution of goal kicks

Sweeper keeper trait (rushes out a lot)
