Chambers, Cork, Lovren and in that scenario Wanyama would be sufficient cover I feel, certainly would be happy for us to sign another young full-back but if we didn't I wouldn't be that bothered.
Indeed, this is the popular opinion and I understand it but personally, like with the right-back situation, I wouldn't mind us getting another but am fine as we are really. Still happy for Rickie to be the main man for 85% of our games with Rodriguez starting to be babyfed into become his successor. Then season after it starts to become more of a jobshare between Lambert and Jay. And unlike a lot of people I haven't given up with Mayuka yet and would be fine with him being third choice and getting more opportunities. I don't wholly disagree with people who feel a new striker is a priority but personally I'm happy as is, 3 strikers for a one-striker system is good enough for me. I'm a real believer in keeping the core chemistry of the team the same and letting our young players develop together with a few key signings and academy promotions rather than squad overhauls, so 3 key first team players would do me just fine.
