Yep, he's known about a fair number of deals this summer already; Nani, Payet, Alderweireld and, it would seem, Schweinsteiger - all just in the last couple of weeks. The guy obviously knows exactly what he's talking about.
I don't doubt we're in for someone big. Only question is, does this Memzdogi guy know all about it too, given that he's said alot more about it?
