He is a very good GK ala Navas or De Gea but I think we have overrated him. He is not elite level ala Neuer, Kahn, Cassilas, Buffon.
I always thought the same, but in all fairness out of all those names Ter Stegen is probably the keeper that had to work with the worst defense and not by a small margin.
Overrated GK, captain material ? Nah
He's one of the premier reasons why we concede bucket loads in CL KO games.
He's king in small LL games but absolutely shits the bed whenever the pressure is on. Not 1 monster game between PSG, Juve, Roma, Pool, Bayern. VV would have come clutch in at least 1 of the 5. Same with Navas and Oblak. I don't even need to mention Neuer.
