Coutinho looked a little rusty vs Sevilla, but I expect him to start this one. Mane will be a loss, but our attack should be fine with Coutinho, Salah and Firmino/Sturridge. It's the defence that we will focus on. Just like the OP stated. We have looked bad recently and we need a strong defensive performance.
Burnley is a must win game. We need to find a way to secure three points. It's games like this one that we have managed to fuck up and I'd like us to show we can do the job we need to do. It's games like this one, wins in games like this, that will put us in the mix for a title challenge. How we respond, after the City disaster and our disappointing points loss vs Sevilla can be important. A win and we're back on track. A draw or defeat and.., well, let's just win, shall we?
