He looks a little bit like bambi on ice whenever he finds himself in midfield with the ball, as the new “Trent role” requires. He probably has enough technique and physicality to comfortably escape pressure most of the time, but he is just not used being surrounded on all sides and often makes the wrong decision and loses the ball. Actually that reminds me of a tendency he has regardless of position - getting into a physical tussle and losing it decisively, so the attacker runs free while Gomez is on his arse, complaining about being fouled.
Other than that, he’s all right
To be fair, he does look better this season, particularly at RB. But he is a more conventional RB than our other options in that position - someone like Bradley or Bajcetic would feel completely natural drifting into midfield, while Gomez only does it because Klopp and Lijnders tell him to.
