Tbf they got Costa for 32m and Fabregas for ~28 last summer and for Arsenal spent ~35m on Alexis Sanchez - when you put it in the context of those then Stones probably seems expensive if you don't watch him regularly.Thought I'd have a look at what some Chelsea fans are saying about Stones. It all runs along the lines of:
"£20/30/40/X million?! It's only because he's English! He's not worth that, Varane/Laporte/Otamendi is a better defender and would be available for less! Despite the fact that I'm only basing this off of my FM/FIFA knowledge, I've never actually seen them play more than a couple of times in the Champions League, Stones is overpriced!"
