What do you mean by cover? If say Dias and Stones are both out at the same time for say 4 weeks can we get by with Walker/Rodri/Phillips and Stones in the Prem without possibly dropping 4 to 6 points...that could cost you a title...or get you knocked out of the CL...especially depending on who you're playing against...why put the club at such risk? It makes no sense to construct a team like ours and leave yourself short for no good reason...to keep money you weren't planning on having and have it only because Ake chose to leave? What if one of the current 3 suffers a long term injury? Now what? Go begging for someone's surplus to requirements to come on...with everyone knowing you're stuck...this has got to be the dumbest, most meaningless, debate I 've seen in some time...if Ake leaves you take that money and buy another CB...if it happens to be for a less or equal amount, great...if you have to add 10, 15 or 20 mil more for an upgrade that works too...what are we talking about?
