It seemed off with me aswell, which is why I spent a good few weeks asking some people on here who I know get inside info if they've heard anything. Everybody came back with the same story, talks in Jan about Robinho, was offered to us for the summer, nobody's sure what the result of it was.
I suppose that I'm overlooking the possibility that we could have all been fed the same info.
EDIT : I very rarely post transfer speculation or anything, but I've heard this exact thing from three different people in my normal life, and two off of here, so thought that there was probably something in it.
