And again: It's not about getting someone in and warm the bench. It's about rotation.
Why does that work so well for our midfield, but couldn't work up top?
Regardless of rotation or warming the bench, we couldn’t have bought anyone close to as good as the front three with just the promise of rotation. Top players want to play and play regularly not be rotated.
Better cover than Origi and Brewster could’ve been bought but we’d still be looking at lower quality than the front three. Klopp must think what he’s got is good enough.
For me it’s easier to rotate in midfield. The partnerships are easier to rotate than those up top. Forwards need time together to know each other’s game to get the best out of each other. Most teams stick with their best partnerships and don’t rotate on a regular basis. Same with CB’s. I remember us all complaining when Rafa barely played the same team from one week to the next and our results reflected that.
