Really hope there's something to the Zinchenko story, would be a very shrewd signing. We can offer him the opportunity to play CM as he wants to, while also gaining some cover for Myko without a new signing (I'm not convinced Nkounkou will make it in the PL). Also, having shown a willingness to play Coleman as a CB in a three at the end of the season signing Zinchenko gives the similar option of playing Myko as a LCB alongside, say, Godfrey and Tarkowski with Zinchenko the LWB.
You don't train and play under Guardiola without developing top notch technique, even Delph looked a cut above most of ours in terms of composure and technique, so you're replacing that quality plus providing defensive options in one fell swoop.
