Sounds to me like Klopp said that injured players will come back but given the current situation they got Caulker and have been looking at options up top. That's very different to the wholesale squad changes some expected and for which a new manager often has the prerogative to do.
Naismith is a good get for Norwich. Long I think of as a faster, but smaller Ings. I don't know if he's more profligate; similar things were said of Ings.
And in the battle versus subjectivity and confirmation bias, here's a table of what players have contributed in terms of goals+assists this season:

I added the total goals/assists in red and consequent per minute figure (plus the red crosses for injured players). So you can argue Lallana is the least consistent of our top attacking contributers, but not by much.
Last season he had 9 goals/assists, ahead of Lambert (8) and Balotelli (7), but well behind Sterling (18), Hendo (17), Gerrard and Coutinho (both 13). He averaged at 320mins per gl/asst which could be accounted for by his injuries. I still see him as a midfielder who has been put further forward because he does know how to score, while Allen/Lucas miss way too much and Can is still learning. But his goal return isn't top notch. We were so good with Sterling and Coutinho in the middle because we could dribble past players to cause the panic/space for the forwards. Lallana can dribble, but overall he just seems too slow.
EDIT: Note that the strikers have understandably better per minute records and all are pretty good. We do score. This is my repeated motif, but I still can't help feeling it is the fragile confidence around the club that is the major problem. Mignolet has one of the best clean sheet records but is widely derided. When Sturridge plays we often score bags of goals and both Ings and Origi have looked like they could be speedy finishers that fit well with the rest of the team (we're yet to see Firmino score using speed, he looks more like the upgrade on Lallana, even if he does have a Kewell-like ability to lose the ball easily due to how often he is trying a lower-percentage options). The team is overwhelmingly young and like Spurs should get better with time, but in my opinion they have a higher ceiling because we are Liverpool and they are Spurs.
