Honestly, Girona winning the league would be an amazing achievement but I believe its far too early to even think about that. We're barely at the halfway point of the season and while Barca and Madrid have had trouble with consistency or with fitness, all its take is a good run to change thing around. Likewise, a bad injury to one of Girona key player or a bad run in a couple of games could see Girona drop in the table quite quickly.
Still, I think it would be amazing from a neutral point of view if they went all the way and did it so I'm kinda hoping they do even if I seriously doubt the realism in that.
Girona have been playing the best football and they just destroyed barca which I love to see. I hope they can sustain this to win the league.
