Looks like the deals for Mustafi and Perez are either close to done or done. David "The Ornacle" Ornstein is saying both players are scheduled for physicals tomorrow (Friday). When it comes to Arsenal news, The Ornacle is the gold standard for reliability. He doesn't comment on transfer deals regularly, but when he does, it's almost always spot on. Whoever his Arsenal source is, the person is clearly plugged in and feeds great info. I know it's too late for either to be in the squad for Watford this weekend, but I'm really damn excited for fresh blood. Mustafi is a helluva long term signing and The BFG's successor at CB.
