Anyone. I still believe there's no way you can't sign a player if you have cash. If they get 40mln out of Eto'o don't count on average players going there.
And then still, they'd need to fit in several key players two weeks before the league starts without a chance to practice much togheter due to the internatinal matches, that will also cost them.
I really think that, assuming they sell both Eto'o and Sneijder, they won't be able to replace them by compared quality this late in the transfer season.
Or they'd have to do it with unreasonable prices.
For example Hazard won't be allowed to leave the club cheaply, season already started, CL is about to start, they know they won't find a quality replacement so they'll ask a huge amount for him, and I feel this will e the case for many other great players out there that Inter might want.
