Mina will no doubt come in as the regular CB, but I’d rather Keane be the one to partner him. I wouldn’t say there is much in it between Keane and Zouma and we already own Keane.
I think Zouma's pace would just edge it for me, depending on the game of course (i.e. if we're playing away from home and looking to sit back a bit, Keane would be better).
But at the moment there's no rush. He doesn't need to be dropped straight in which is a good thing. If Keane/Zouma drop out of form then we have a very good back up.
