Barcelona coach Ronald Koeman says he's in the dark over reports of signing Daniel Alves.

With his contract expiring at Sao Paulo, Alves has offered himself to Barca.

The former Barca fullback has spoken openly about returning to the Catalans. Asked at today's Champions League presser, Koeman said: "No one has told me about him or the possibility of him coming, so I don't like to answer about this."

Asked about what he would deem a good Champions League campaign, the Dutchman added: "It always depends on the circumstances and the moment. It is not normal that we are required to reach the quarterfinals, semifinals and final. What you have to do is win tomorrow, that's what matters to me now. Because we have lost two games."
