Injury restricts defensive options available to Freddie.
Freddie Ljungberg is not going to be able to go with his first choice back four against Man City on Sunday afternoon.
Kieran Tierney is definitely out and Hector Bellerin will be assessed prior to the City game and of course, Rob Holding is out for at least another couple of weeks.
This means that Sead Kolasinac is almost certain to start on the left and if Bellerin is not passed fit then Ainsley Maitland-Niles will most likely be given the right-back spot.
I cannot see Freddie changing the back two of Sokratis and Calum Chambers. They were far from perfect against West Ham but certainly look better paired than either of them with the hapless David Luiz.
So, the backline I see Freddie selecting against the champions is
Sead Kolasinac
Calum Chambers
Sokratis
Ainsley Maitland-Niles
The only real change I see to that lineup would be Bellerin ahead of Maitland-Niles in the event the Spaniard is past fit. However, if Bellerin is not passed fit and Freddie lacks the trust in Maitland-Niles then there is an outside possibility that Chambers is put on the right and Luiz drafted in. I just cannot see Freddie doing that though. But never say never with Arsenal.
I am fairly confident, however, that Freddie will go with the back four I have listed. Based on the available players to the Swede I cannot see a better, more suited defence to face City.
That said, if Ljungberg gets the Unai Emery syndrome and decides to go all pragmatic he could end up going with three central defenders and then all bets would be off. That would be nothing short of an invite to City to attack at will.
