Wanting to move from Hearts to the Premiership isn't 'greedy', the SPLs a 3rd rate European league and Hearts are a pretty small club by European standards. If any player outside an Edinburgh born Hearts fan sees that as the pinnacle of their ambitions they need their head seen too.
No problem with ambition but maybe start keeping it to themselves instead of being so public about it and talking at length.
It is becoming irritating and it never used to bother me really.
When this attitude is widely spread, and quite openly and regularly, I sometimes think it's too much in the players heads about what's in the future for them and possibly a bit more commitment diminishes.
We aren't a halfway house for players to come and play a few decent games then think they are ready to jump. Some actually get ahead of themselves too.
