Not sure if these have been reported elsewhere here but "O Jogo" - a leading Portuguese football source (I believe) have reported this:

(roughly, Saints bosses (Reed I presume) were in Lisbon yesterday to present €12M offer, which was rejected both due to the amount and the way in which the fee would be paid).
RE: Belhanda, I found this.

No idea how trustworthy, but it says that Besiktas have a deal agreed with the player, but he is stalling as he would prefer to go to England, where Saints and Fulham (weirdly) are allegedly interested.
