Two of Bellingham's best attributes are his physicality and work rate. It's not something to be dismissed, it makes him a perfect player for gegenpressing. And Bellingham isn't as much of a goalscorer as you seem to think he is, he's scored 1, 3, and 4 goals in the league in his respective seasons at Dortmund. Not in a way that makes him different than Wijnaldum, anyway.To me it looks like he does his best work when he’s getting into the box scoring goals. He’s a Gerrard/Lampard type to me.
I think you have to give him freedom, Wijnaldum did a huge amount of defensive work covering for Robertson, you don’t drop 100m plus on a player for him to do that.
People would have said the same about Haaland, that he isn’t the typical City style of player. I think Pep is evolving their style to be more direct. The best roles for JB are the Gundogan role, or Xhaka role at Arsenal (never going to happen though).
For me he's Wijnaldum with his technical and physical attributes boosted, which is a world class player, and a perfect fit for Liverpool. Like I said though, he's the sort of talent that you adjust for.
