You don't do a trial run with the key international team. If someone wants to try a female coach in the men's game, let them try at club level. Do well, take it from there. Just thinking you can transfer the skills is crackers, different environment, entirely different level.
But there’s been male managers of the female teams… the sad truth is you’re right but perhaps for the wrong reasons. Down the years I’ve seen great engineers, admin staff and sales people promoted to management positions and then fail miserably.
And we’ve seen it time and again with great footballers failing in management positions. They have the experience playing at the highest level, Prem, Champion’s League and international level yet bomb completely.
There will be a female out there capable of managing at the top level. What will stop them is fear, testosterone, male ego & plain male chauvinism. But whichever female gets it the first time will make Southgate’s crucifixion look like a picnic.
