I'm going to say the politically incorrect thing that some are avoiding - Sturridge is not our best forward. In fact, we do t have one molded into the game we play. Firmino plays there because he's better suited to the pressing style. Origi would probably come 2nd,and he presses well too. Sturridge doesn't. He is an excellent forward, arguably best English one, but he needs the team to play differently. He makes excellent runs off the ball now and then, and the team benefits from that, but the rest are carying him for most of the time when he is on the pitch. Leaving a hole uptop easily propagates in the middle in our style, and that carries the opposition pressure deeper that when Firmino or Origi are playing.
Daniel, please learn to fucking press! Pretty please!
