Fernando is a good tackler and pretty good one-on-one defender - which is why I think he has a role in our side this season. I think we're in agreement :-)
Not reading the game is failing to see where a pass is likely to go and moving accordingly or failing to see that a teammate has left a huge opening and providing cover. Fernando seems entirely incapable of this.
Looking straight at a man, charging in and anticipating where he might pass the ball is different - this is more instinctive than actually being able to read the game - Fernando seems to be good at this.
It's a curious thing though - until I rewatch a game, stopping action and reviewing play to assess blame and to evaluate player positions - it's really hard to figure out just what's going on and who is doing well and who is really screwing up.
The first (and only so far) match I've done this is City versus Spurs - it's only after I reviewed the action frame-by-frame so-to-speak that Fernando's weaknesses became crystal clear.
Maybe I'll do the same for the latest Darby - but probably not. The Derby was a really strange game - most of our best players didn't start, and as a result, passing was awful and pressing broke down. The entire game failed to follow Pep's philosophy (keep the ball, high press to win it in their side, attack,attack, attack).
I'm not sure that there's any reasonable conclusions to draw from rewatching that game.
