I'll definitely say MU is a finished club it they do that. They's still keeping their contract with Ten Hag alive, and why don't they bring Ten Hag back to the club? I lose my logic to understand the sense of this team.
If they sack Amorim, then sign Emery, i see nothing different in this coach subs. The better they told Ten Hag to take the position as head coach.
Manchester United is scared if they might enter relegation zone if the manager is still Amorim, but they forget that they signed Amorim because Amorim was successful with Sporting Lisbon.
Unai Emery is quite successful with Aston Villa, but it doesn't mean he will successful with Manchester United.
Emery once trained Arsenal, but he was not successful.
