I disagree entirely with this I'm afraid. First of all, we wouldn't need to score 3 or 4 goals per game if we had an actual goal 'keeper' in nets (witness Joe Hart versus Lionel Messi from a few years ago). And secondly, when it comes to the referee, one thing we can say is that he is never going to be on 'our' side - that is a fact. He might be bent, straight, competent, incompetent but never is he there to help us or assist us. At the very minimum that is an 'agenda' that is not in our favour, and some of us think there might be even more to the 'agenda' than even that. We must work around that problem (as Roberto Mancini evidently discovered) - don't dive in inside the box or you are giving the referee a chance to award a penalty (Fernandinho at Chelsea), don't retaliate in front of an official by nodding your head into the opponents head as you are giving a chance for the referee to send you off (Nasri - plenty of times etc), don't commit two yellow card offences in succession (however minor) because you are giving the referee the chance to send you off (Gareth Barry plenty of times etc). And always play your strongest side, that preferably gives no hope to the opposition.
This is how it is.
The only thing we can say for certain is that our manager is supposed to be on our side. That is a fact. However, it could be that Pep has had an agenda all of his own, and one which transcends whatever the referee might be up to and which we (the fans, and possibly the club) are looking for. When Roberto Mancini brought Tevez back he did it for one reason, to help us win a trophy no matter the cost (to his reputation): every other manager we have had from Allison to Reid to Royle to Keegan would not have done that for us.
Its the same with Pep and the Bravo situation; from my (angry) perspective, Pep was more interested in winning the cup with Bravo to prove a point, than he was in winning it purely for us, the fans. This was the risk he was prepared to take on Sunday, which is why he filtered Bravo back into the side in recent matches, for no other valid reason. For Pep, winning the cup without Bravo would be a damning indictment of everything he has stood for this year and it simply wasn't worth the risk to his reputation. This might sound harsh but I've seen it before with too many city managers, to know that it happens: ask yourself why Peter Reid sold both Clive Allen and Colin Hendry if you doubt me. If you still doubt me, look up the Revie 'plan' from the 1956 FA Cup final (aka Spurdle's Boils) to see how close to the wire these decisions actually get. We are talking FA Cup final 1956. We are talking Denis Tueart dropped for the FA Cup final replay in 1981.
So why worry about the referee, when you can't even be certain about the agenda of your own manager?
Here is how it happened. Joe Hart got dropped and loaned out for no good reason. We trusted Pep that his replacement was going to be a significant improvement (benefit of the doubt and all that), we found out eventually that he wasn't, via the most damning set of statistics you could ever, and I mean ever, encounter. Pep had to respond by switching keepers just to take the heat out of the situation for a few games. Cabellero comes in and does a good job, but then gets dropped for no reason: the plan for which, evidently, was for Pep to bring back Bravo for the cup again, despite all the odds and all the statistics.
On Sunday, we went out of the cup because for seemingly the millionth time this season, the only two shots on goal went right through the keeper like he wasn't there: was anyone here surprised? I doubt it, and so it wasn't like we haven't been warned.
I cannot blame the referee for the fact that over 120 minutes, enough water slopped over our prow to sink the ship - maybe the ref was there with a ladle in his hand. I am much more concerned though with the hole that someone evidently decided to drill in the bottom of our hull before a ball was even kicked; that's the worry.
I'm glad I'm not running this club because for certain we have a manager that is out of anyone's control: good luck with that - it will be needed.
