Agree with much of that, Klopp is quite harsh, he really has not allowed any of those subs a consistent run of games to find adequate form. They are just given a chance in an odd game or a few mins here and there. Part of the blame must lie with the manager. I dont believe that Origi or Shaq are as bad as made out to be, the later produces for hia national team and is a key player. Also getting pissed off with him not using that Greek guy and even Ben Davies, how fucking bad can they be ? Its one thing to obsess about fitting into the system etc..but you have to consider using the resources you have. Its not like these later two have not played professional football at a decent level prior to joining us.You're right, although Klopp's unwillingness to use Chamberlain/Shaqiri/Origi/Minamino is a factor here. They haven't really been given many opportunities and Klopp seems to persist with Mane and Firmino out of habit at this point.
It could be because they're shite, but I do think some of them would have surpassed some of Mane and Firminos performances this season. Whatever, though, at least two of them should be sold and just sign the best finisher we can. That's the only metric I want to see from a new forward. Someone we can stick up top in a 4-2-3-1 and bury chances for fun.
