If Poch, Potter or Southgate happens to be Ten Hag replacement it will prove to me nothing has changed and the people making the decisions at this club are as incompetent as ever.
For every single manager you can find reasons why yes and why not.
De Zerbi; unproven, played nice football with Brighton
Klopp; not available
Pep; not available
Poch: failed in last job, good spell in Spurs
Tuchel: failed in his last job, serial winner
Jose: in decline, won everything
Don Carlo: staying in Real
Simeone: too defensive, excellent coach
Southgate; not good enough in club football, good spell in NT
Potter: failed in Chelsea but played nice football in Brighton
Xabi: signed new contract
McKenna: talented, completely unproven
Amorim: talented but unproven at biggest stage.
Every manager is a risk these days.
