Konate and Matip can help with that. Morton’s brain is his advantage. I feel that Hendo and Thiago can both play the role, but neither is natural. You saw the gaps against the barcodes, that will be punished if they do it against Spurs. I could be wrong, but that’s my take on the situation.
We weren't swashbuckling against Newcastle in attack as well, in fact, we were gifted a couple of goals by Newcastle themselves. I wouldn't take one game as an example of anything let alone gaps in Thiago's or Hendo's games or their ability to play a role. Thiago made two unnatural mistakes in that game, that's where the buck stops.
Konate and Matip cannot vacate their positions to help Morton win duels in the middle of the park, a big problem happened when Lovren tried to win duels for Can and then we were punished in certain games for that a few years ago. I'm happy that Klopp has solved that problem for the most part.
Morton is a good talent, he may be able to play one of the CM positions in PL, but to play the DM position, he needs to bulk up a bit and get to win a lot of duels (ground and air).
