Who plays left-back?

With AEK (6) out injured the left-back position is up for grabs. M (3) has taken on the role in pre-season, proving a more than suitable option with excellent performances vs Assumption and SHT FC. New to the squad SIN (19) has something to prove, but with his natural position being left-back and having pace in abundance is it his time to shine for the black and gold? Who starts, you decide!
