The difference in Bilić quotes on this deal compared to Cipré are quite telling.
Absolutely, a massive change. We do need an aerially dominant defensive stopper and leader next to Ajayi, I've seen nothing of Ivanovic in Russia but if he can still hack it physically then he brings those attributes to the table. Bilic has certainly got his man here so no excuses from him.
Bilic did say with Ivanovic we now have the right numbers and quality at the back, I personally think we are still overstocked by one unless a back 3 is our default formation, which I am not convinced it will be. I think these are our first choice back 4/5 scenarios now:
O'Shea Ivanovic Ajayi Gibbs
Furlong Bartley/Hegazi Kipre Townsend
Furlong Ajayi. Ivanovic O'Shea Gibbs
Phillips. Kipre Bartley Hegazi Townsend
Phillips as a right wing back could be a shock but he played there quite well under Moore. Even if a back 3 is our default formation, I still think I'd sell a centre back, if it is a back 3 Livermore could slot in as a secondary option - he has played as a centre back before at Hull.
