@CroJack ... nothing against Brewster, Gallagher, Guehi ... but with them and Cabango and Dhanda et al, we're asking boys to do the jobs of men.
It's a demanding enough league with a seasoned team of quality pros. A kid here, a kid there, fair enough, but we're asking a lot from kids playing their very first series of senior games .... and they're not getting a lot of help from the touch line. Roberts is in his second full season; same with Rodon and Celina. And, VDH, Ayew, Naughton and Routs can only do so much. Grimes is over his head as captain.
As you point out, Bielsa is having his struggles also, but he's been there, done that and knows what to do to remedy. Andy Pandy dealt with kids for a few days or a few weeks at a time and just had to organize them into some sort of coherent unit ... against other kids ... and then send them home as healthy as possible. All of the heavy lifting was done day-in-day-out by the coaches at the respective clubs.
