Zlatan Ibrahimovic is yet to talk to Barcelona regarding personal terms, despite there being an agreement in place between Barcelona and Inter Milan.
His agent (incidentally, the same as Maxwell's) is quoted as saying to ANSA,"The two clubs have found an agreement, now we'll see. As Zlatan said, if there really is a concrete interest, the deal could be done. But I have not yet spoken with Barcelona, I haven't been involved in any negotiation, I haven't signed anything, I didn't do anything so far."
However, there is no cause for undue worry, as this merely means that Ibrahimovic and Barcelona will be sitting down to talk, and will probably agree on a contract very quickly.
The only possible pitfall to this deal is Eto'o rejecting the contract with Inter.
