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.
