A good friendly to change things up and try something new. I say ditch the old school orthodox of a 4-4-2 formation and go with a 4-5-1 or a 4-3-3.
My starting back line would be:
It gives a chance for our strongest 4 in the back to gain some chemistry with each other. Later on, try new guys out like T. Xhaka, Vangjeli, and Hysaj.
Abrashi, Basha, and Kace should start in the CM. Later in the friendly, bring in Vullnet Basha or Gjasula.
Rama and Llullaku on the wings. Try out Vajushi as a sub.
Cani or Sadiku as our CF.
For the first half, I want to see our strongest starting 11. They have no played a real game with each other for 2 months, so I think it is important to take this game seriously and gain chemistry. Build a comfortable lead, then experiment with new players for the rest of the game.
Our strikers suck.
EDIT: Do what tkez said and cap as much players as possible. Amir Abrashi, Vullnet Basha, Taulant Xhaka for sure.
