I believe he should be Top 10 in the world right now, especially with his ball playing skill and passing accuracy (long & short), and not to forget he is a good shot stopper. He actually even showed how well he handles crossing yesterday, with all those punches. (good directions to where he punches them.)
for me, he is definitely better than Costa (his is only younger), Ederson, Sanchez, Stegen, Pickford, Martinez .....
Others are more debatable, but I think his market value is low only due to the doping history.
