Don't know if you have had a chance to look back at the Flanno pen incident? In my opinion it's a 50/50, can see why it's given, but if given against you you're mad.
The ref cannot see the incident as Diame is obstructing his view. He should not give a pen as hence he can only be guessing.
This season we've had some luck with official's decisions, in previous seasons we have been consistently mugged and lost games in the same situation. The incident you speak of was not a split decision as you imply, that may have been the case if discussing ball contact but the fact is the 'keeper actually had a full grip of Flanagan's ankle, preventing him from continuing play, the ball was still available and at his feet, that describes a penalty moreso in the penalty area.
At the moment of contact, ref makes no movement to indicate pen award (perhaps he's waiting to see if Danny scores.) At this exact moment Suarez turns to the ref, and strongly gesticulates he thinks it's a pen. Did this convince the ref? Did Suarez 'buy' that pen? Is that cheating?
Suarez was claiming only the result of what transpired ie the player was brought down unfairly. How is that cheating?
I don't know if it's cheating, I don't particularly mind it but it's unsportsmanlike and many will say cheating because it's an attempt to win an unfair advantage.
That's what Carroll did, he won an unfair advantage, and to many people he cheated.
Is there a great degree of difference between the 2?
If not the mock outrage at Carroll and lack of any comment on the antics of Luis is hypocrisy...debate
Such contact with a goalkeeper is a penalty all day and if the ref had a clear view it would have been given, to make a comparison with Suarez claiming for a legitimate call is not acceptable, Luis has been demonised in the past for simply claiming legitimate fouls missed by the ref, as we know he is a target for the less skilled who have no answer to his brilliance; consequently their only answer is foul him.
Manager's of the less skilled players try to gain an advantage by bad mouthing Luis; any which way to block competition.
