The great profit doesn't get them very far. As ajiz138 pointed out correctly, it will not be easy for Inter Milan to find a goalkeeper of the same class.
Goalkeepers in general are hard to be found when they really want one who belongs to the top 10 or even top 5 in the world. I would say that even a top 10 goalkeeper is not available right now and if one was available, it would cost more than 50 million. I think it started with Alisson Becker that transfer fees for goalkeepers also went up and are now closer to 100 million than they are to 50 million.
But if Inter Milans wants to attack again in all competitions they have no choice but to find a goalkeeper of the same level.
True it is hard to find but they are still goalkeepers at a good level that hasn't been in much targeted yet by the clubs like Livakovic. Take the situation of Mendy until he was approached by Saudi club. Mendy was bought below 20m Euro and Livakovic also is having interest but none at the level of Inter with around 7m Euro bid. Yes, it is bit hard to find but if they have good scouts then I think they really can find themselves a good buy. I hardly see much competition between the clubs when it comes to buying a goalkeeper as compared to players at other positions.
It is a bit different for goalkeepers because it is possible more often that a good goalkeeper goes undetected for a while and more focused scouting is required. For a striker you can just have a look at how many goals he scored even at a younger age. Not that this is the only statistic that's important here, but judging a goalkeeper with potential is a bit more difficult than judging a striker. The younger the player, the more knowledge and intuition a scout needs. There are good goalkeepers out there but it is also one of those transfers that come with more risk whether the goalkeeper was the best choice or not.
