While I have no objection to Tierney - he is having a good season - he reffed our game v Leicester only 2 rounds ago and the charity Shield in August. Even by the PL’s standard of erratic appointing this does seem excessive
With Norwich having had Rob Jones for 2 successive home games, I'm not sure that they even look at previous appointments and it just seems to becoming the norm that each club seems to only have a small pool of referees appointed rather than the whole group.
