Poch's training methods are the same as Bielsa's, and so far in decades of testing show ability to effect parts of season, lift sides to a point, but has never turned a side into winners. Maybe the players have realized that after 5 years, they aren't getting any better and the only advice their manager can give is run harder ...
Have you never worked for someone who's advice/direction you know from experience simply isn't going to work? this is what the squad is saying right now seemingly, and Spurs fans and pundits are saying well maybe we should get rid of players and get in new ones who haven't figured it out yet, so will just run into a wall again for Poch .. makes no sense.
