Marcus Thuram signing is a really profitable one for Inter surely. Because they signed him on a free transfer. As you know they have been in need of solving the issue of lacking strikers after Dzeko - Lukaku duo both have left the team at the same time. It was quite fast that Inter brought a decent striker already like Thuram.
Thuram and Martinez can make a decent duo hopefully. But as two centre-forwards have left the team I wonder if there will be another striker transfer for Inter. I don't think they are broke now. Whenever we talk about their potential transfers they are said to have bad finances.
However I think Inter are currently in a good financial condition to make bigger signings.
Yes marcus thuram is a very good signing inter milan did. Moreover, Inter Milan did not spend money to get him because he is a free transfer player. The Thuram signing is also believed to be a suitable replacement for Inter Milan should they fail to get Lukaku back. I think the management job of inter milan is quite good in shaping the squad because they have got the right players for their front line.
Even for Lukaku, Inter Milan have again approached Chelsea to try to borrow Lukaku for next season. Thuram and Martinez will be a stronger duel on the Inter Milan front line next season. I think inter milan will be the strongest team to compete with napoli in the scudetto race.
