It's a strange one, because he's never really had a run of games before. Brendan has always favoured a front 3 previously (with Perez on the right, eurgh), and Nacho was never going to start over Vardy. I get the impression that Rodgers never really rated him - quite a few games where Nacho would score/have a good game, only to be dropped after a poor 45 minues the next game - and he's only now getting a run of games because of the injury to Barnes, in which he's now made himself undroppable.
It could go either way though. It's one of those where quite a few times you see him shooting from miles out at you think "why on earth are you shooting from there" - but it seems to work. Whether that's luck or skill, I guess time will tell. He's always had a wicked shot on him, but his link up play is coming on in leaps and bounds now, which is promising.
