So given the fact that the best attack wins the league more often than the best defence (certainly in the Premier League era), goalscorers on a team make a big difference to league-winning hopes, and the more of them you have, the better you will usually do.
An elite rate of scoring is to score a goal every 180 minutes or less. So looking at the top 6, we can see which teams have the potential to cover for their team-mates when the chips are down. Looking at each team, here are the numbers (excluding players who only scored one goal):
Liverpool - 4 players at 180 mins per goal or less. Unfortunately, Sturridge is one of the four. Even more unfortunately, Firmino isn't. We need more goal output from him, because outside of Sturridge, our three elite scorers are Salah and Mane (obviously), and Shaqiri. And with Shaqiri not an automatic starter, we're relying on two players right now to get our goals, and one of those has had a drought the past two games. We need goals from Salah against Bournemouth to get him back up to speed
City - 4 players at 180 mins per goal or less - but Jesus has been out, so they've had the same problem we have right now, i.e. relying on 2-3 players. But Jesus is back, so they are up to full strength, and Mahrez needs only a little improvement to bring them up to five. They have to the tools to win this league if we let them
Chelsea - 4 players at 180 mins per goal or less. One of those is Higuain, though, who has a small sample size, so it remains to be seen. But not playing Loftus-Cheek regularly is possibly holding them back, so unless that changes and Higuain maintains his level, they'll probably stick around as a top four challenger and no more
United - 3 players at 180 mins per goal or less. Lukaku, Martial, Rashford. Get them on the field at the same time, and they have the means to put on a good run. Any two of them gives them a chance too. But Sanchez is a wash. Any time they play him they're an attacker down, for all intents and purposes.
Spurs - 2 players at 180 mins per goal or less. Kane and Son. It's not even worth guessing. They are dogging their way through the season, but ultimately - unless Lamela improves a bit and they actually play him - they will probably end up falling a bit short
Arsenal - 1 player at 180 mins per goal or less. Without Aubemayang, they are struggling, although Lacazette is at 181 mins per goal, so if his form can get consistent, then they can push on as a top four challenger. But outside of those two, they are in schtuck.
So for us, a turnaround in Firmino's form will be a huge boost, and maybe using Shaqiri and Sturridge more as impact subs in stalemates is an idea for Klopp to consider, as they add goals on a consistent basis.
Hopefully that upturn can begin against Bournemouth. A hat trick would be nice, both for the campaign, and for his numbers.
