Apart from a very few deals I think quite a few will have been done already. But in principle. Ie Milner to Villa. It all depends on players going elsewhere which may not be ironed out until after the WC. I haven't seen the club officially welcome Berson back into the fold so it seems they are still touting him around France awaiting a buyer. Again, something may have been agreed somewhere, but the first player who goes will set the whole thing moving, this will probably have been done by now without the WC. Don't forget most clubs close down around this time and peope gone on their hols. So, just because the WC is on it doesn't mean there are more people around to do football dealings with.
