I can only pray that by tactical switch, he doesn't mean trying a back five again. It never, ever works.
I hope what he's actually talking about it is outnumbering and swarming Neves and Moutinho in centre midfield, otherwise it's going to be a massive struggle against a team that will happily knock the ball around until gaps open up for quick counter attacks.
If Godfrey is fit, get him in at left-back, shift Kenny to the right and bring
Branthwaite in for Keane.
It's vital that Keane and Coleman are dispensed with.
