Do you really think managers should ignore the players attitude towards staying at the club when picking their teams?
Do you really think that's what I said?
I'm saying that if you don't want to be at a club, you don't just get benched. You get sent to the reserves or out on loan. Every player in the match day squad needs to be committed, otherwise there's no point having them there at all, regardless of who else is available.
You seem to be claiming that an instagram message prompted Solsjkaer to employ a policy where Matic can't be in the starting eleven, but can be on the bench, which is just weird.
In any case he's started 3 of your last 4 games, when other options were available, so it's obviously not true.
My guess would be that Solsjkaer wanted someone a little more mobile in midfield against Man City. Whether it was the right decision or not is another discussion.
