Yeah I agree, the 2 of them compliment each other's games really well, reminds me a bit of when we had Alonso and Macherano in the middle of the park in the sense that one's a terrific passer and the other is great at breaking things up and winning the ball back.
I thought the third CM AOC had a solid game as well, he put in a proper shift and made some vital blocks and tackles, as Carragher said on commentary that one where he blocked the header inside our 6 yard box was a great bit of tracking back which probably saved a goal. Tracking back like that shows he is working hard off the ball, it's not always noticeable but in that instance it was.
