First off, with a lot of those players it's been to soon to say whether they are successes or not. How the feck can you say that Emre Can is or is not a success when he's played less than five games for the club? Saying there's been 25 players brought in doesn't account for the players that we cannot judge yet. Bit misleading. Same with saying 220m has been spent with only 3 successes. 120m of that was spent this summer and, really, it is too soon to tell who out of that group will and won't be a success.
I think it would be very contentious to say a signing has been successful at this point in the season. Rojo looks awful, but I don't think it would be fair to write a defender off when he's played less than ten games for his new club. I won't be doing that with any signing just yet, I'd give them at least a season and even then you have to keep in mind that players can turn bad seasons around (see Henderson and Lucas).
Lallana, Moreno, Can, Manquillo and Origi (for Lille) have all looked good out of this summer's business. I'm not sure what you mean with Manquillo being forgotten soon, he's looked a very good addition and one that I and most other Liverpool supporters hope we make permanent. You're judging a 20 year old Markovic when he's played less than five games in a new league and missed most of pre-season. That is ridiculous.
As for players on loan, you've just gone and massively made that section up. Origi and Ilori are both rated massively by the club. You've not seen any of Ilori, have you, so how can you say he is or isn't likely? Ibe is also rated massively and he will definitely have a big future at the club. Teixiera has been a late developer for his entire career and has been one of the very few bright spots at Brighton. He likely won't make it here because we already have a lot of talent in his position, but we'll turn a profit on him quite comfortably I expect.
Balotelli in the bad camp already...
Coutinho was still very good last season and his first half-season he showed brilliant form. Yes he's inconsistent, but what players not named Ronaldo, Messi and Suarez aren't?
