Stopped reading here because it's obvious you've never seen Maicon play previous to this season.
Whats your point exactly?
Are you trying to say a tactically aware manager can't tell Maicon for ONE GAME to stay back, or play a DIFFERENT PLAYER, or tell the winger to double up on Bale.
Maicon sucks balls defensively, like Alves, Ramos and several other "world class" right backs, who are deemed so mostly for their scoring records than their defensive ability. Ashley Coles scoring record for instance, is terrible, utterly terrible, but he's world class, for both his defensive and offensive play.
But then again, obviously, you infered something I didn't say, that somehow that isn't Maicons game. Its all well and good playing that way against a team without crazy pace.
Mourinho would never in a million years knowing exactly how Bale plays(its not a secret, its not unpredictable) would have contained it by means of probably doing what almost every armchair fan in the world worked out, keep Maicon back, or play a more defensive player, double up on him, they managed it against Messi, and Iniesta, in the same game.
EDIT:- Have you seen City play, a team that was somewhat freescoring under Hughes, with many of the same players, become goal shy under a different manager, or most importantly, a different tactical idea for most of the same players? How one player prefers to play isn't the way they have to play, ever. For the record, Carlos could tackle, and defend, as can a lot of Brazillian fullbacks, the current batch are basically wingers, Alves plays more as a winger for both club and country now for that very reason. That doesn't mean Alves has never doubled up and stayed back under managers orders.
