Reed saying Puel is the man. Let's hold that. No mention of Black, which is interesting.
Doesn't make sense that Black was employed largely as a translator for Puel. Much cheaper to hire a sessional translator as we did with Poch. Black's role and influence clearly substantial and possibly damaging.
If Black's the problem rather than Puel, sack him. Then strongly and publicly back Puel, and sell persistent trouble-makers in the team, whoever they are.
