Look forward to that problem when all our midfielders are fit and good to play. Certainly not the case right now.
I would be surprised if Salas does not start against Perth, unless something unexpected comes up. What position, that can be sorted out before the game depending on who is fit. That is also why we recruited him, for injuries and for extra depth.
At this stage Rufer may not be fit, Pennington might be. Also, if Payne is not fit, Salas plays RB, giving Mo Al-Taay a spot in midfield with whoever else is fit.
Perth are on the rise, and it never is an easy game over there.
