Think Klopp will slowly bring in Danny, Sakho, Klavan, Origi and the young lads as the season progresses. They'll feature more and more. It's a long season and the second half will see all of the above, including Can and Grujic as more regular features- with some kids sprinkled here and there.
It's no surprise he's been telling them to just get on and get their heads down.
Our "best XI" will start to tire- some will get injured due to all the running and other issues, Mane will go to the AFCON. They'll all get a chance.
When this happens we need to have Moreno, Sakho, Ings, Ojo, Stewart, Can, Grujic, Ejaria, Lucas, etc help carry us through late December, January, Februray when the others have started to recover.
