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.
Marcus Thuram is a good attacker and his signing will surely be a bargain for Inter and the fact that he was signed for free makes it even greater deal for the Milan club.
Inter Milan who aren't sure of retaining the services of Romelu Lukaku at the club for next season needed to get a forward player that can play alongside Lisandro Martinez and luckily for them Thuram who was out of contract with his former club was discovered. Inter Milan might be currently facing financial challenges but I think they are handling the situation very well
