If we put out the same team we did against Arsenal there's a very good chance they'll drop points, because it is what they have done against the 'small' teams for the past 3 months. Yes, they were excellent against Arsenal, but Burnley aren't going to play like Arsenal did.
We've seen that same team falter against the Burnley's of this world too much recently, I'd definitely throw at least one change in there (Origi). Doesn't necessarily mean that Firmino has to be dropped. We had 80% possession against them at Turf Moor so it's fair to suggest it'll be roughly around the same amount at Anfield, a CM can be sacrificed.
