I'm not saying you necessarily need to buy one, although obviously that's going to be the quickest fix, but you need a couple of players that make your opposition really think about how they're going to set up. Whether they're brought in already established or step up is neither here nor there. I personally don't think any of Lallana, Firmino and Coutinho are going to be that sort of player. They're good, and are working very well in Klopp's system (at least at the top end of the pitch), but none strike me as capable of being a real gamechanger. Mane has that look about him at the moment, and another good season would cement that, I feel.
You're top scorers by one goal to a team that's got a game in hand on you and has conceded eighteen fewer goals. You've been one of the better attacking teams, certainly, but it's no good if you can't keep them out at the other end. As you say, defenders should be the real priority for you.
