What’s the issue with this if the player consistently performs for your team, and there isn’t really any viable alternative (depending on what you think of guys like Tomori ect
Two massive issues with the decision to send Maguire on v Scotland are this...
1) as meaningless friendlies go it is the least meaningless going! It is however still a friendly and one goal is to give players a try out to see how they perform for the national squad. This was the perfect chance to put fikori on, let the public see him, prove he is in your plans and ensure the flights from Italy were worth it. He will not be buying in to the England experience right now.
2) more importantly most nations are not aware of the extent of the Maguire debate. Scotland very much are. Scottish fans are also known to excel at being wind up merchants. It should have been obvious to southgate that this was not the game to have either Henderson or Maguire on the field for. As it is there was no duty of care and thought generally when bringing him on. His arrival on the pitch meant more focus on Maguire and more on the sense of Southgate.
I can see why Southgate picks Maguire, he has performed even when his club level has been lacking. Sticking with someone you trust should be commended, throwing him under the bus however is simply idiotic.
