It's not really lost to Roma. It was Inter's decision not to sign Dybala. We chose Lukaku over him and then couldn' find room anymore for Dybala.
Dybala would be here if Antun didn't fight in the negotiations (salary, commission etc) too hard in June. Lukaku opportunity appeared and we picked that. More than anything, it's Dybala's loss as his agent is too incompetent to see how the market works. He tried to bluff with his hand which wasn't too good hand as we see now, there was really not a proper market for Dybala (as he ended up t Roma
)
