Who plays right back?

PANG (12) had been suspended up until our last game vs TOA, in which he was outstanding, With his insane work-rate causing issues for quality opponents. However TAR (21) was an excellent understudy in his absence, staking a real claim for a starting place. Now to totally confuse matters another TAR (15) signed this week, after really impressing in the trials … we’ll call him NEW TAR (15) for this reason! Who starts at right back is your choice!
