I reckon retiring any number is a strange thing to do...
Imagine any team retiring the No 1 in memory of a goalkeeper?
I understand the sentiment and it's not a slight on Marc, my mate worked at the hotel he was living in in Manchester and said he was a great bloke, but there are other more appropriate ways to remember past players even if they do go tragically.
But since the decision's been made then it would be difficult, politically, to justify using it again since all the over-emotional hand-wringers would kick up too much of an indignant fuss!
But if anyone could wear it, then Big Sam's the man!
Perhaps this could be a sticking point in negotiations... Not over the No 23, but over the No 9, since that's what he's synonymous with. But as we all know, the Boj has that and I wouldn't expect him to give it up too easily, if he is staying after all? But if Eto'o does come then he's well down the pecking order and might be vacating it anyway... So this question would then be redundant.
We'll see, but I've had more than a sneaking suspicion, after some ITK info last December which got me "Listed", about Eto'o, so I'm certain we're in with more than an outside shout at getting him, since we've been in the hunt for a long time, so he certainly knows he's wanted at City, which as we've seen with other (actual and potential) signings, is a big factor in a player's decision. That and the huge wads of cash obviously!
