Assuming you mean Paul Travis. He left last season but was a Performance Analyst rather than Recruitment Analyst so different role.
I assume his responsibilities now fall to Claire-Marie Roberts
Should never have been brought in. Was always going to be impossible to do what everyone wanted with it in such a subjective sport & so, as you say, has actually damaged the game irreparably. The genie is out of the bottle now though sadly.
Don't think Howe would leave Newcastle or the FA would cough up the compensation needed tbh. Would expect Potter or Carsley.
Potter has supposedly turned down quite a few clubs recently, I wonder if he's had an eye on this the whole time.
