Pretty sure this is why Arsen replied like that. Yeah they are selling tons of shirts and they are making $$$, their actual profit is not totally different to what a lot of media/fans imply.
They're making a decent amount of money at a pretty fast rate. The biggest reason his shirt is selling so well is because Colombian's are buying it in droves. So I don't think it's inaccurate to say Colombian's will fund a pretty sizable portion of the transfer.
