I'd be tempted to revert to a McGhee style squinty 442 for this game.
Gillespie
Tait Aldred Hartley Taylor-Sinclair
Bigirimana McHugh Campbell Frear
Johnson Sammon
Cadden needs a rest but Frear isn't a wing back so playing him there doesn't do him or the team any favours. If playing three at the back then Taylor-Sinclair or Livingston should play left wing back.
Just feel that Frear started the season well and creates chances more than anyone else in our team so would like him in the team but not at wing back...
