Don't think I'd be concerned with a Moore/Mousinho partnership - that would still be a good pairing for League One.
Obviously I'd rather Dickie stayed, because he's become the best Centre Back we've had since Matt Elliott (maybe.....I was an Andy Crosby fan as well, and he was a great defender, but a little less cultured than Dickie).
But if we do get an offer that's too good to turn down (and for me, that would be upwards of 2 million), then the key once again will be who we can recruit as a replacement. Because unless KR has a lot of faith in Nico, we can't play half a season with just two senior central defenders.
