The last two seasons saw Watford bring in players from the Premier League, the Championship, Serie A, La Liga and others. They were sent down.
Bournemouth brought in players from the Premier League, the Championship and La Liga. They were sent down.
Last year the only Premier League player Sheffield United brought in that wasn't on a free was Lys Mousset. They stayed up.
It's not where the players come from. It's who the players are.
