My idea is to play Montoya. Sure he doesn't have anything particularly special about him at the moment, but he recognizes his role is as a defender first. On very many of the goals we concede Alves is nowhere to be seen while the rest of the defense is getting ***** on the flank he should be defending. Remember that clasico where Messi scored his hat trick? Both of Benzema's goals came from crosses from Di Maria, who was completely unmarked because on one of them Alves wasn't even close to getting back to position and on another he was slowly trotting back despite being able to reach him if he were to sprint. This is without even taking note of the rather stupid foul he committed on Cristina that somehow was ruled a penalty. He was literally at fault for every single goal we conceded yet you'd rather play him over Montoya, who hasn't actually been given any chance whatsoever to prove he can play at a high level. And I'm going to stop you before you inevitably try to say that was "One game", because it's not. It's one of dozens. His lackluster performances are often brushed under the rug because we might win a game he was shit in or because our CB pairing screwed up in a far more noticeable way, but aside from the Man City games (Where he was far more effective attacking than actually defending, which luckily we had very little to do) he hasn't stood out as a player worthy of maintaining a place as a roadblock to our next generation.
Alves is seriously the worst part of our team during most games and I'd sooner play Patric in the CL final instead of him. Half the time even having someone there to apply pressure would cause the attacker to make a hastier move that wouldn't result in picture perfect plays coming from our right flank on a constant basis. Everyone and their grandmother goes on and on about how badly we need a new CB, but to be quite honest, we are in far more desperate need of a RB who doesn't hurt the team with a typically useless offensive effort and a practically nonexistent defensive effort.
