Those names you named could be around the same level, I am not arguing about that, and top 10 is a stretch but I can put him at 10th place. But remember that this is a dude that played in Croatia national team and Dinamo Zagreb, no big team so far and he is already 28. If he was one of the best, he would have been bought by a big club already.
Ederson, Alison, De gea, Courtouis, Lloris, Der Stegen, Neuer, there are many goalkeepers I could still name that are better than him, these players played at the top teams and won top awards with their teams and they deserve to be considered much better than Livakovic without a doubt, they are definitely not even close in talent, I would consider livakovic one level below those type of big club goalkeepers and still good, just not as good as them.
Again, I need to disagree. In my opinion, Livaković is at the same league as Marc-André ter Stegen or David de Gea. The fact that he is playing for Dinamo Zagreb should not be used as a tool to attack him. He is playing for them since 2015 and the reason maybe that he just want to stay in Croatia. Anyway, I would stick to my arguments. Without Livaković it was not possible for Croatia to get past Brazil during the quarter-finals of Qatar 2022. During regular time, he made some spectacular saves, and the way he saved the penalty kick from Rodrygo was just amazing.
