Barcelona sports chief Andoni Zubizarreta concedes the past week has been "tough".

Barca have been banned from the transfer market for 12 months over their deals for junior players.

"Our model is not a new one, but one that we've been working on for a long time, and will continue to do so," argued Zubi.

He did admit that that the Club had faced a "tough week" due to the FIFA sanction, which in his opinion is "over the top".
