Card-Happy Referees in Big Games

Sorry for the long post in advance but I would like to hear some of your guys viewpoints on this so here goes..

I've noticed a trend and in my mind it's not a good one - It seems to me that in Spain, Italy, France, and to some extent Germany, the style of officiating doesn't translate well to Champions League soccer.

There are some obvious differences in the way matches are officiated among the different major leagues. The referees in the Premier League seem to allow more physical play than their counterparts in the other big leagues. Refs from other leagues typically call more ticky tack fouls and tend to be more likely to give out a card or fall for a player overreaction or dive. These differences are ok in my mind. To each their own and by that I mean if this refereeing style is uniform across one league, the players know whats up and adjust their games to play within the rules. But when some of these refs are officiating Champions League matches, the carryover of that style of officiating results in varying levels of what is acceptable as a card-worthy offense. In my opinion, the English style of officiating makes for better games. There are less stoppages, better match flow and most importantly, less frivolous cards which totally change results and end up ruining what would be great 2-leg tournament soccer play.

A great example of a way I think a match should be officiated was this past weekends Manchester United/Chelsea game. The ref in charge of that one - I can't think of his name - but he's the bald-headed, dumpy dude. i thought he was fantastic and it resulted in a great game.

Both legs of the Bayern-Real Madrid are examples of the opposite of that. Cards are given out early forcing players (except for Vidal and Casemiro, of course) to be more apprehensive. After that, it turns the rest of regular and then possibly extra time into an exercise in anxiety from a fan perspective. I find myself just sitting there waiting for another player to exaggerate an iffy foul or blatantly dive, only to then be rewarded by the sending off of an opposing player. IMO it ruins what should be simply a couple of the best teams in the world battling it out to advance. It's quite frustrating.

My question is this: How can this be fixed? Why aren't there more strict rules forcing referees to conform their style so that the officiating will be more consistent across the board for a tournament involving different teams from different leagues?
