Hi Ruben
If you are reading this, you must be really desperate for a solution to your problems.
Nevertheless. Here is my suggestion, what you should do to prepare for the Newcastle game:
Stick with Onana. Yes. I know, but Bayindir was even worse. Talk him up. Force him to watch his best Serie A moments ten times a day to get his confidence back.
Rip Bruno of his Captainship and let him fight for his place. He does not deserve special treatment anymore.
Move Anthony to the LWB-position. He is the only left-foot with the attributes to potentially do well there. Make him cross till he drops in training.
Let Amad or Dalot play RWB. It is obvious, that Dalot is wasted on the left. The guy can´t cross with his left foot if his life depended on it. Let them cross till they drop in training. I prefer Amad, because he will try to beat a man. We are lacking that.
Mazraoui was really good at LCB. Move him back there. If it ain´t broke, don´t fix it.
Maguire and De Ligt are both good in the middle of the back three, but don´t play them elsewhere. They are slow and will get exposed. (Play both for the Liverpool game though, where we will stand deep. They are really good at dealing with crosses.)
Keep Yoro in for speed. He has not been that good, but he needs to play to get anywhere. There is a good player in there.
Ugarte is out. That is a problem. He fits your system almost as good as Hjulmand did at Sporting. Talk to him about taking too many risks though. He is collecting way too many yellows, and that is hurting us now.
Casemiro is slow, but he is still the best option to replace Ugarte for the Newcastle game. He is also an asset on corners.
Mainoo has lost his mojo this season, and should be benched for a while. With Bruno and Ugarte out, your first instinct will probably be to go with Eriksen. Don´t. He is too slow to defend the Newcastle/Liverpool midfield, and he is also needed elsewhere. Let Martinez play here for the Newcastle game, He can pass, and he can win back the ball, which is what we need. We really need to get a new player in for this position in the January window.
Eriksen should finally get to play at 10, setting the attacking players up. This is his best position, and he can still do real damage here. We only got control/composure, after Casemiro and Eriksen came on yesterday.
For the other AM-position it is a toss up. If you go with Dalot at RWB, I would play Amad here, but I would rather see Amad on RWB. That leaves you with Mainoo, Zirkzee and Garnacho. I really miss Mounts skillset here, but we have to do with the players available. I would start with Zirkzee and bring Garnacho on at some point.
Rasmus is our best and only 9. He is starving at the moment, and you could see his frustrations with the service yesterday. He was really mad at Mainoo and Amad for not getting it right on a couple of occasions in the first half. Michael Owen called the 9 at United for the most difficult striker position in the PL at the moment due to lack of service. I think he is right. Set Rasmus up, and he will score.
This would be my starting 11 for the Newcastle game:
Onana
Yoro-Maguire-Mazraoui
Amad-Casemiro-Martinez-Anthony
Eriksen-Zirkzee
Højlund
Thats it, Ruben. Now it´s up to you.
