I think we have a problem where we have a Sporting Director and a Manager who seem absolutely blinkered to all options once they get their mind set on something.
Toli has shown that where he chased Koop and Todibo all summer, willing to pay whatever was needed and ignore all options, including Huijsen as an alternative once it was clear we wouldn't get Calafiori because he had his head set on selling him.
We also have Motta who seem set on one single tactic, no matter what players are available. Even his substitutions tonight, you could tell they were thought out before the game and he made no consideration that Mbangula was the one player causing problems tonight and should have stayed on.
