I know you haven't. Some other posters seem to be on the verge of forming a anti-Firmino camp though – we've seen this with many players over the years and it's never pretty when posters get sucked in into "pro" and "against" camps.
One positive thing I'll say about Lallana is that Klopp always needs at least one player among the attacking 4 who is not just good, but GREAT at pressing and covering ground. In Dortmund that was usually Grosskreutz. So far Lallana has shown great willingness to run himself into the ground for the cause; you could make a case that all that extra defensive work has affected his attacking contribution somewhat (surprised Ryan didn't make that point yet), but at the same time that's precisely why he is getting regular minutes under Klopp. Lallana was excellent at Man City; in fact I liked his defensive contribution so much, I selected him in my top 3 ahead with goalscorer Firmino missing out. So, maybe if we stop expecting him to be our playmaker (I think his chronic ball-hogging tendencies pretty much disqualify him from that role in Klopp's fast-paced game) and instead think of him as a defensive-minded attacking player, maybe he can still become an integral part of this team.
There are other players vying for the same role in the team though – Milner is one, Ings could be one when he is back and Hendo, for me, has the best combination of creative talent, strong physique and work-rate to win a consistent place in that front 4. If Firmino doesn't turn it around soon, I could see Hendo actually taking his CAM spot, with Coutinho and Lallana/Ibe/Milner on either side.
