Hearing the Cavani stuff myself now on Twitter.
Does seem within the realm of possibility as I know PSG are looking to offload some players as FFP has screwed with some of their transfer targets. For example, they want to sign Di Maria but have been prevented from doing so already because of FFP. Also they could only sign Aurier on loan because signing him outright this season would have been too much. Cavani is rumoured to be unhappy as well.
Wasn't fond of him after his WC displays but as it stands with just Giroud and Sanogo leading the line for us I'd take him. He'd need to take a substantial cut from his 300 k a week though.
