I would have removed Brown, Flint and Collins and gone with: -
Bacuna Morrison Nelson McGuiness
Pack
Colwill Vaulks
Giles Harris
Moore
In a 4-1-2-2-1 formation with Giles and Harris out wide and played through Pack and Colwill.
It's not ideal but how would you have fixed Mick's car crash of a team last night if you had taken charge at half time?
