It’s a cert Rafa will focus on Martina as our weakest link, whatever you think of Rafa he always focuses on opposing teams obvious failings and Martina playing out of position is ours.
Newcastle this season have struggled against teams who use the flanks so it’s essential at least one of Rooney or Gilfy is moved and replaced with Lennon/Mirallas/Lookman/Vlasic
I would also consider dropping DCL, not because he has done anything wrong but Newcastle don’t suffer from his type of player, they struggle far more against pace and Niasse or Sandro could be a better option.
I also think we need to be careful with fatigue.
We could see the game against Huddersfield we suffered with fatigue after 2 games in 4 days, the same could be true on Wednesday.
We have a few players like Schneiderlin who could fresheners us up by replacing Davies who was our worst player vs Liverpool.
