Correct me if I'm wrong, but I don't think Blackpool even HAVE a reserve team playing.
In which case why is everyone getting so butthurt about them putting out a 'reserve' side? Why have 25 players registered if the PL are going to fine a club for fielding players who aren't in the regular first choice matchday squad of 18? If they are all in the first team squad they are all eligible to play first team football.
Obviously the wealth/resources of the club will have a bearing on the strength of the rotation players, but for the Premier League to say that clubs like Chelsea and Man Utd can make wholesale changes to their side for a league game to rest players for the Champions League - a competition so bloated and far removed from domestic football its untrue - is fine, but clubs like Blackpool can't when the fixture computer spews out periods of congestion, because it demeans the precious Premier League, is at best double standards, at worst f***ing corrupt.
Villa played four non-first choice players from the start and had another five on the bench. Should they be fined as well? As it turned out, Blackpool could and possibly should have got something out of the game, so the players they brought in were competitive.
