Remember back when the club was sold and the new investors made it seem like their new capital would mean Inter wouldn't have to sell its star players? Turns out that might not exactly be the case. Out of the blue Wanda Nara, Mauro Icardi's wife and agent, gave an interview in which she said that Inter is putting Icardi up for sale due to financial constraints.
It seems that Icardi's performances during his time with the Nerazzurri has aroused interest from a couple of clubs and due to that interest he asked for an improved contract even though he just received a new one last year. Some reports suggest that Inter refused this and that is why he is being put up for sale. Other reports do not mention this contract issue and simply state that a cash shortage at the club is forcing Inter to sell one of the larger assets. In the interview Nara suggested that Icardi wants to stay but the club is forcing him to move on.
There are two possible explanations for what is happening here. Option one is that Icardi and Nara want an improved contract for the 23 year old and since Inter refused, they are peddling him on the market in order to force Inter to make a decision on him. They know that the fans love the Argentine striker and would be furious if he was sold and are using this to twist the club's arm and either give him that new contract or ship him out.
Option two is that Nara is completely correct and Inter is selling Icardi because they simply need the cash. For me this makes little sense. The Suning Group arrived and gave the club a large cash investment which was supposed to make sure a situation like this was avoided. They talked about how they want the club to not only reach the Champions League but compete for the Scudetto and Europa League title, selling your star striker and arguably best player is the last way to go about this. As talked about before the new owners knows that Mauro is an incredibly popular player and signing off on his sale would do nothing but piss off the fans and potentially poison the relationship before it has a chance to develop unless they plan on buying a top striker to replace him (which wouldn't make sense because it would cost just as much to sign a replacement as it would to sell him).
Hopefully somebody that works for the club will release a statement soon to explain what is going on because this has the chance to explode in everybody's face if things are not handled well.
