Dzeko is certainly not a bad player, but does not come close to the level of Lukaku. I think he's a lot older too. Lukaku is more explosive, faster, more dynamic and also scores a lot more. But it's better than nothing. And maybe he will do well at Inter. Or maybe Lukaku will just come back just like in the past.
What you say is true, Edin Dzeko is one of the strikers who is quite good especially he has scored almost 119 goals from a total of 260 matches in all competitions while playing for roma, but as we know now Edin Dzeko is 35 years old and of course the performance and his stamina has decreased enough, will he be able to replace Lukaku role as the spearhead of Inter Milan in this season?
Moreover, it is reported that Inter Milan will also sell Lautaro Martines and if Lautaro Martines moves to another club, automatically Dzeko will become Inter Milan only main striker this season, and of course it is not an easy thing for Edin Dzeko.
