We need a centre half regardless of Stones staying or going so im not against Williams signing. Its clear that Koulibaly is a Stones replacement so, like i say - Nothing wrong with bringing in Williams. Has a better injury record these days compared to Jagielka it seems, which is a shame, i love Jagielka.
I dont think he's a Stones replacement either. If we get £42.5mill for Stones (assuming the fee is £50mill) then we could possibly have signed Williams and Koulibaly for an outlay of around £8mill, which is very good business.
