Nope.
The point is that if Lucho doesn't like a player, or something then you're out of the system.
And diving could be one of those things. The guy probably watches these games closely, or at least more so than other teams with Gijon being HIS team.
It could be one of those things as much as any other thing anyone here would suggest . there is nothing to back this hypothesis up tbf .
In fact our player are always accused of being diver,complaining a lot.exaggerating a lot of plays under him by many neutrals .never mind Neymar type of in-game enjoyable tricks that many doesn't like in Spain and keep accusing him of disrespecting opponents.
Lucho won't like Alen if he isn't a useful player ,not b/c of dives or whatever kind of those things .
And Lucho hasn't been here for so long to even be sure that if he doesn't like a player he won't change his mind .
In fact there has never been a player who has proved Lucho wrong for now .
There is actually a chance he just knew better than fans and not a stubborn as we assume
