Mackay is likely to start as the key forward, but will Forsyth, Richardson or Armstrong get the nod?
Forsyth has started twice, and is yet to score. Richardson started on Wednesday following two sub appearances without a goal. Armstrong has made two sub appearances, but failed to make the bench on Wednesday night.
Armstrong, it is rumoured, has been carrying an injury which has limited his playing time, but could he be fit for the trip after the mid-week break?
Another selection is on the right wing. Martin Brittain seems to be prefered to Jamie Harwood, but it was the later who scored the equalising goal on Wednesday night.
The backline might also be changed, with James Curtis, Carl Jones and Chris Swailes battling for the centre back partnership, and left back Phil Cave trying to make the team for the first time this season following the arrival of Mark Robinson.
It is unlikely any of the midfield trio of Wayne Phillips, Kris Gate and Phil Turnbull will be dropped, but what if the formation changes?
Bogie has favoured the 4-3-3 approach in the past, but what would that do to the line-up? Gate, Turnbull and who in midfield? The likely option is Alex Francis wile the only two possible options are new signings (but yet to appear) Neale McDermott and Christoph Ascherl.
Again, in the past, wingers have been used to partner a lone striker. So it would put Brittain or Harwood on the right, Phillips on the left leaving Mackay up front.
Crawley could be make or break for the team, even this early in the season.
Gateshead Squad: Provett, Farman, Baxter, Robinson, Cave, Curtis, Swailes, Jones, Pelonde, Harwood, Brittain, Phillips, Gate, Turnbull, Francis, McDermott, Ascherl, Mackay, Armstrong, Forsyth, Richardson.
