I went for 451 to reduce the threat from the flanks and crowd the midfield.

Full backs operating as full backs to stop that threat Celtic have getting in behind defences. Each fullback in my lineup has cover in front of him, Stephenson on the right and Trapanovski on the left.
Holt part of a 3 across the middle to deny space for the likes of McGregor to play through us. Babunski despite being off the pace recently does have the ability to surprise Celtic with a ball into Dalby or Trapanovski.

I don't expect Goodwin to use 451 though.

To be honest we'll probably lose whatever formation, the main thing is that we play with high energy, high commitment to close them on the ball and compete physically by putting in hard challenges. And where's Docherty when you really need him...
