Losing Dybala and Bremer was always becoming more and more likely to happen the longer it would take to get rid of Sanchez/dzeko/Corea and sell Skriniar for a proper price. Inter are paying the price for getting a finished Dzeko and a completely useless Corea last summer, if they had spent the total amount (transfer+salary) of those two on one single proper forward last summer (and used a cheap loan or youngster as 4th forward), they would be in a better spot now to have signed Dybala.
Im not quite sure why some people mention the Lukaku deal as some kinda block for any of the above though. There is absolutely no way Marotta would have signed Dybala without getting rid of Sanchez first, regardless of Lukaku. Lukaku was a sudden unique opportunity to replace useless geriatric Dzeko.
People should be happy Lukaku was signed for a year atleast, Dybala would still be a Roma player today if Lukaku hadnt joined, since Inter have failed to get rid of Sanchez/others. Getting Lukaku back for a fairly low fee, for a role thats far more needed than the one Dybala occupies was too good to let pass. Signing Dybala with the risk of not getting Sanchez/dzeko out is too risky.
Losing Bremer is sad, especially since Skriniar will likely be sold anyways and then some midtable donkey like Milenkovic will be signed.
Rough times ahead for Inter, both in attack and defense. But the midfield looks good atleast, Aslani and Mhki will be decent upgrades. Inters season will rise or fall depending on if Lautaro and Lukaku can play atleast 85% of all matches. The backup forwards are a disaster tbh, Dzeko is so finished its not even funny and Corea in all honestly is a midtable table player at best.
