I don't think anyone is saying he's far and away the best possible 4th centre half choice for any club in the world though are they, so that's a bit disingenuous. We offered contracts to Young, Doucoure, DCL etc and the list of people we're supposedly interested in for right back (a position a lot of people have seen as an area we need to improve as a priority) are all free transfers. Reading between the lines, we just don't have a lot of money to spend, and they believe resigning Keane is at least as good an option as signing someone like him on a free. It's a long way from ideal, but realistic it's always looked like something that might happen, and for fairly obvious reasons.
