You can't really tell how aggressive Liverpool attack will be. They have nothing to lose whether they win the match or not. Arsenal will play with their last strength to make sure that they secure three points in this match. Otherwise, they might found themselves on the third position. I hope that Arsenal wouldn't finally end up going to Europa League next season 
They are rivals, and no supporter before a match would want their team to lose to their rivals. Because of that, Liverpool will put on a show, and I think they will defeat Arsenal. On the other hand, even if Liverpool loses, nobody will care as much, but if Arsenal loses, it will definitely be all over the memes.
