MDG was clearly an opportunity move. They saw a very good Italian keeper come up for a reasonable price and went for it early. Otherwise we're kicking the can down the road to next summer where there might not be a similar keeper available for that price. Giuntoli also seems to love MDG, judging by what Galliani said.
I'd also argue against any moves for the end of August, where possible, but we'll probably have to make at least one if we are trying to overhaul the squad. Yes you can grab a bargain for players who clubs want to shift, but if it's a player they don't want to sell then you pay over the odds. Maybe the club is thinking the likes of Sancho might be more affordable deeper into the window, but opportunities also disappear. I'm more concerned about the players we'll be trying to move at the end of August, and the cut price deals we'll end up conceding. The club have clearly made it known now that several players aren't part of their plans, and so we can't expect top dollar for any of them.
