If Jenkinson plays RB, I think there's a good chance that Downing could crucify him. Or at least necessitate one of the Arsenal CBs babysitting him, which would leave more space in the middle for Suarez and Carroll. Of course we need possession of the ball in order to attack them.
Oh, and set-pieces: we really ought to be able to create goal-scoring chances from corners and free-kicks against Arsenal.
Not nervous yet, but I will be. A win would be FANTASTIC.
