With David Luiz suspended and Alex almost certain to be left out who will we play in the back 4 against City? There is the obvious back line which is Bosingwa-----Ivanovic----Terry----Cole But that back line has never won us a big match and with that combo we are all over the place. Ivanovic is not as good in the centre than he is on the right where he is completely solid and enough has already been said about Bossy on the right hand side. Silva and Aguero will have a field day, so assuming Alex does not get considered we have to go with this. Ivanovic------???????----Terry----Cole But the question is who do we play in that vacant CB spot? as it will be a player out of position. Here's a few ideas. Paulo Ferreira - ONLY JOKING Ryan Bertrand - He has played there a few times before and he has the pace Terry doesn't and that could come in seriously handy against Aguero. It's a risk granted but i don't see how it's a bigger risk then playing that dreaded back four combo which has never won us a big match. That or put Ryan at LB and Ash in the centre. Oriol Romeu - He has got good defensive qualities and AVB said after the Fulham match that (after Alex's red card) Oriol moving down to centre back was a option. If that's the case we can move Oriol down to CB and place Mikel in defensive midfield. Nathaniel Chalaboh - This would be a huge call and a huge shock by AVB but remember (ironically against the same opponents) Dalglish doing the same last season bringing Flanagan in for his debut against City and it payed dividence, maybe AVB could do the same here? That are the option if Alex does not play. Although i don't see why we can't play Alex, he is still on our payroll and he will surely want to give himself a good send off and a goodbye to the fans, what better way to do it than play a blinder against City?
