The Porto ace priced himself out of a move on Friday to Spurs and AVB says a January deal is not on the agenda.
"We were warned to the fact that the deal could not be closed, keeping in mind that Porto is a difficult club to negotiate," said AVB.
"We managed to reach an agreement quite late, but there were problems with the contract ..."
Asked about revisiting things in January, the manager added: "It's extremely difficult. Let the speculation aside for a moment. We have a whole season ahead."
