Some will no doubt allude to some sort of conspiracy theory what with Chelsea FA Cup semi final against Villa where Villa should have had a penalty and Terry sent off.
The advantage of TV replays means that nothing in this game goes unnoticed any more whereas, there and then at the time of the match, the officials have just the 2 views. Maybe they didn't see it? I don't know.
Chelsea just seem to be getting that massive bit of luck at the right time of the season.
