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?
