Always difficult to predict these games. The worry, is that Arsenal will want to recover the points they'll think they lost against West Ham. Liverpool have looked decent without hitting a stride. With Henderson out, the team is certainly weakened, irrespective of whether it will allow Firmino to come in. He's a big game player, and Firmino is still settling.
Liverpool's front six will be very interesting when it is announced. Arsenal's team could be predicted easily right now.
Have we been watching the same games? 2 games, one individual goal and one offside goal. In the home game I don't think we forced any saves from their keeper of any note. If I remember correctly, we only had about 2 shots on target. I wouldn't say we've looked decent. The only positive I could see was that we got two good results.
