TAA has been really good, he's supported well, spotted the danger and bailed out his centre backs (or notably, Matip) a few times. Ditto Robinson.
Milner has been good too. Can gave the ball away in dangerous areas four times that I counted, he played a couple of good forward balls and got the goal, but his general play in our own half has been atrocious. AOC has made a few good turns and breakaways but he needs to do more to support the attack, he's a good player who can turn quickly and make stuff happen, he needs to believe in himself more and stop playing it safe.
Karius again has been really good, hopefully his progress continues.
