It seems this Memzdogi character did a Periscope stream last night where all he did was walk around zooming in on Rolls Royces whilst not saying anything. Either he's trolling us all badly now (with all of the abuse he's gotten you'd have to ask if it would be worth it though?), or he's basically aware that the cat's out of the bag and is just making sure everyone knows he knows without outright saying it. He's since deleted the video.
You'd have to think that the player Muzzi Ozcan was on about in his original 'signing of the season' tweet was Marco Reus. Whether he's talking shit or not, time will tell.
