We'll never know with Hummels, he made no noise either way. To make no noise at all tends to nudge towards "is interested". Vidal was supposedly interested but also doesn't mind staying with Juventus (doesn't want to break the bond he has with Juventus fans by asking to leave).

As for prices, well, United only spent £4m for an international defender than you did. These things happen. You also spent a lot of cash for many players over the years as you've pointed out. So do all clubs in the end. You can look at the Torres/Carroll deals and call them flops, but what if they had worked out similar to how Ronaldo worked out for Real Madrid? They could have been steals. Yes, I consider the Ronaldo sale a steal for Real Madrid. Wish we'd sold him for more! I consider Rio at £30m a steal for us. But I digress, the only thing that can justify a price in the end is what happens after the buy, so we'll all just have to wait and see, and for our own teams, just hope it works out.

I do see £16m as reasonable for Rojo. I can see Di Maria at £56m-73m (the numbers are going up and down like crazy) being justified given we needed a world class talent and he was one of the only ones available that was willing to head to a CL-less team. Herrera and Shaw are similar for me to Di Maria in that I'll need to wait and see.

Overall we'll just have to disagree regarding what prices can and can not be obtained.
