We made €10m to sell half of those players, but don't forget we spent €9m to get them outright in the first place. So we won't feel the financial benefit until the end of those agreements.
It depends on the interest, really. He said he's going to leave and that he is unwanted, and so far there hasn't been a lot of interest. Monaco already bought a LB (Abidal) so hopefully that should rule them out. Benfica seems to be the most interested club, but PSG could of course change that. I don't think 20M is impossible unless PSG or another oil club shows interest. So far it seems fairly quiet.
