Almost no top manager plays two players fully in the first line of attack these days, whatever the terminology; most of the game sees one of them moving just on the edge of midfield, balancing the opposition, working. Klopp is the same.
Our potency next season depends a lot on how the staff rate Origi, do they see him as someone good enough to lead the line at the top level consistently? They must get their call right on this one for goals to not be an issue, as it was for a good period of this season until Sturridge returned and Origi stepped up.
Sturridge is a non-issue, he has the quality, only his final physical condition will determine whether he's to be number 1 again or 2nd choice striker.
Firmino can work behind the striker, or in certain games, provide tactical variety as a striker.
Certainly encouraged with what the first two have brought to the team since their return, but wouldn't be surprised if we saw a new first choice signing there either, that position is far from nailed down.
