I think a lot of the posts have it right to varying degrees - a couple of time in the game on Sunday he charged forward at a man with the ball only for the player to make a quick jink and get past him. Credit to Emre for then hustling after the player.
However, he also had several plays where he battled for the ball and won it, and laid off nice passes to retain possession or keep a move going.
And the one opportunity where he not only won the ball, but discarded Dembele (a player that people were raving about when Spurs got him) then burst up the field and astutely got it to the right player - Sterling - was the kind of play that should show his potential. Energy, drive, combativeness and a good eye for a pass.
I disagree that he won't feature - I think Rodgers targeted him for purchase because he knows his game and knows that he can improve it. I think he will be played as much as possible (not starting apart from the League Cup) to get him up to speed in the PL.
(Also good to see the overreaction post Manchester City has died down).
