Everybody was brilliant yesterday (especially the CBs), but we definitely need to give special mention to Milner.
He's a midfielder playing LB so he's never gonna be perfect, but he's come up against Willian (+ Ivanovic) and Mahrez and made them look average.
Not only that, he's still getting forward and putting in quality crosses.
Still a long way to go and many tests still to come, but perhaps Klopp was right about not buying a LB?
