How much further? Are we realistically expecting Danny Sturridge to score what, 27 league goals this coming season? I say this as a person who's always advocated Danny Sturridge and enjoyed watching him play, but I don't think he's good enough (yet? perhaps) to score 27 goals. And bear in mind 27 is only 6 more, that leaves a shortfall of 25 still to be made up from Suarez.
Lower sides haven't defended at Anfield against this team like this before. To say "oh well we've been good before" is massively overlooking the main thrust of the argument, which is that this Liverpool team thrives on the counter and ripped people apart with it last year. If the opponent leaves one up top and two banks of four in their own third, this Liverpool side's main weapon is massively neutered. We saw it with Chelsea last year, I bet you we'll see it again this year. Essentially, your own success had wised people up. This Liverpool side is quick and industrious, but still lacks an artist to pick teams apart from deep, and that's where it'll hurt you the most.
Very true, but I'm not sure it's enough. I know it's a supposition to 'what if', but if City have a main striker out - like indeed they do with Negredo - they can get by because they have such depth in quality, with Aguero and what not. United likewise: if RVP gets injured, they'll play Rooney there and draft in Shinji to fill the gap. With Arsenal's new signing of Alexis, they've sorted their depth problems up front and secured two starter quality in every position. I'm just not sure Liverpool have that. A player goes down and the dropoff in quality is reasonably big. Gerrard goes down, who replaces him? Emre Can? Lucas? Joe Allen? Likewise, Sterling turns his ankle, who takes up the mantle? Suso? Jordon Ibe? You get my point. Where Chelsea can replace Eden Hazard with a high quality Prem left winger like Schuerrle, Liverpool could replace Coutinho with Oussama Assaidi. That's the real problem with Liverpool's depth.
That's something of a fallacy though. Without Suarez you won more games than with him, but your chance creation was way lower (like half lower) and you scored fewer goals. Seemingly the only major thing that changes for the better statistically when Suarez isn't in the team is your win rate, which all stinks of a low sample size throwing off correct results.
Replacing star player with a handful of not as good ones, building depth but not necessarily depth in quality (arguably Spurs did more of the latter, in fact), bringing in no defensive reinforcements (again, Spurs actually did bring someone in, and needed to less). There's more than a few ways in which it's similar business, really.
