The only thing I think will affect Atletico Madrid is that since they played match today against Borussia Dortmund, most of their players may be tired playing Girona just within a short time after the champions league game.
Girona since this season has been in their good form but then they actually didn't have that capacity to Maintain a form around the top of the table because they don't have that stamina and form thst can actually give them such form enough to be able to stay long enough at the top of the table and keep them to be there long enough rill the end of the season and so they got displaced mid season a d since then they have been unable to get back to the top of the table again and have been struggling around the top four buy haven't fallen off within thst position.
Borussia dortmud didn't actually stress atletico so much to be an excuse for them to not be able still be able to play their league games and still win where necessary buy the problem is thst fatigue is something we cannot just skipp but then we definitely have to find a way around it which i think most definitely they will be doing because they still need maintain a good stand in the champions league so Incase they are unable to still continue in the champions league they can be sure to qualify again.
