Not sure. Recall something about his wife’s illness being less painful in warmer weather so they went to Australia during our winter. Agreed he doesn’t seem to miss a match so things might have changed, nevertheless he still wants a deputy.
Given TB spends half the year in Australia he probably wants to formerly appoint a deputy so reporting lines are clear when he isn’t around (and to clarify who ISN’T his deputy)
TB thinks and acts long term so I expect he is planning for things that we haven’t even thought of.
Good move to issue a hands off message to other clubs/football bodies.
