There has been no indication so far that Spors was in any way involved in the spying. Even if you say he should have known... how would he if they tried to keep it a secret?
They may view him as the best option to get the club promoted. Not like he'd be likely to spy again given what happened this season.
Would they sack a player if he cheated in the playoff semi-final vs Middlesbrough by diving to win a penalty?
