Under normal circumstances, it is fairly easy to guess what line-up the manager will go with and you can then craft a match preview based on that guess, however, that is not so much the case with Arsenal right now.
I have no idea how many changes Unai Emery is going to make, there really are a ton of open questions with no answer until Emery announces the team tomorrow.
I cannot know what sort of frontline will be fielded, will Luiz be brought in at the back? what is the formation? Ceballos, Nelson, Willock, Torreira, will they play?.
However, that does not mean that I cannot be confident that Arsenal will win at home with the squad they have, because I am very confident they will win.
Bringing in Luiz and say dropping Chambers will not weaken the defence, picking Torreira over Willock will not weaken the midfield, playing only two of Pepe, Lacazette and Aubameyang will not affect Arsenal strike capabilities and so on.
We are not talking about Emery fielding a team fit for the Carabao Cup, no, we will see a very strong Arsenal line up tomorrow in some form and one that will beat Burnley.
I am not being complacent, I know the Clarets will pose a threat, they have an in-form Ashley Barnes and they will be very physical but Burnley have lost nine in a row against Arsenal in the Premier League and there is a reason for that.
I am not so confident that Burnley will not penetrate the Arsenal defence, I suspect they will breach the backline at some point but the Arsenal forward line will simply be too strong for Sean Dyche’s men to hold out for the whole game.
In conclusion, I expect a clear Arsenal win.
