I doubt Arsenal would announce a deal at this time of the day.
There's been some twitter chatter that Sahin was at Colney today and yesterday(but not from the two I trust most).The hiccup(however big or small) in the deal after the weekend seems real now. But I hope it's been resolved. I'm feeling much more positive now than I did last night.
Hopefully we'll have some news tomorrow. We're getting close and closer to the end of the window and we still have a lot of players to shift. Should be a busy week and a half coming up.
