I'd take the £50m and run personally (even if we got a £40m - getting our money back - I'd take it).
He's a good lad and has been decent enough when called upon, but he's very replaceable.
I've made the argument before, but that 4th choice CB slot should be going to someone like Mbete, Harwood-Bellis, Doyle.
We don't need another £40m player to give us 1500 minutes of so-so performances over the course of the season. Take a punt and put some trust into one of our own - we have some incredibly talented CB's on our books already.
It won't happen and we'll go and spunk £50m on Pau Torres (who I think is bang average), but I'm confident we will be back in the same place in a couple of seasons having this conversation.
