Favoritism? Iniesta Cleared To Play

UEFA's disciplinary committee will not suspend Iniesta for what was possibly a deliberate yellow card picked up against Shakhtar during the 1st leg QF match. Several months ago Mourinho and Co. had action taken against them after a similar report was presented by UEFA officials.  

Iniesta (Right) will play. 

For those not aware of these rules in discussion; if a player receives a yellow card in one match, it carries over to the next match, if they receive another yellow card during the next match, they are suspended for the following match although able to continue in the actual match they are in, which then resets your count back to zero. Iniesta received a yellow card during his previous match against Arsenal; now against Shakhtar, Barcelona had a 5-1 lead in their 1st match virtually guaranteeing themselves a semi-final place, at that point Iniesta received a yellow card, his 1st of the game but 2nd in total which meant he would be suspended for the 2nd match against Shakhtar. This meant he would return for the 1st match of the semi-final with a clean slate. 

Now I don't think Real Madrid should be disappointed or anyone in particular for having Iniesta available. If Barcelona is missing any of their pieces not only will they use it as reason for a possible defeat but others will and in this heated rivalry the Madridstas want all the satisfaction they can get. Alright, so I suppose that's the fair-play view that isn't shared by many. Anyhow, regardless of that there is something more important here.

UEFA ruled that Real Madrid deliberately incurred cautions in order to benefit themselves.

Have Barcelona somehow received preferential treatment in this case? Perhaps Iniesta's yellow card wasn't deliberate and he, despite being one of the more intelligent footballers in the world, had a lapse in judgement which saw him commit a dumb challenge in a match where his side were comfortably leading 5-1. I'm serious. I'm curious to know what evidence was available to acquit Iniesta. 

UEFA punished Real Madrid not only for their actions, but more importantly to set an example... Or so we had come to believe. It appears now that UEFA may have simply wanted to show clubs that they too have muscles and not to forget who is really in charge. In this scenario though, UEFA has seemed a little more relaxed as to not suspending one of the best player's in the tournament for a crucial semi-final. 

My position is that I'd like to see him play; I want to see Barcelona and Real Madrid put forward their best starting XI. However, what I don't want to see is UEFA being contradictory to such actions as it undermines their entire organization and creates caution between themselves and clubs. 

Your thoughts, please?
