For me I would be rooting Liverpool as I want to see City drag back a little on the table as we (Arsenal) will be able to enjoy a good lead on the table.
As much as I'd love to watch City stop getting all those points, I honestly dont think Liverpool is capable of winning against City in their current state though but its going to be on Anfield so small chances that this game could ended up being a draw as Liverpool has been keeping insane record of not losing any EPL games in Anfield so far
Still will bet on City to win though
