The fact that Girona is winning every game they play in makes their performance seem surprising to me as well, but I don't think they can win the league because Real Madrid, Barcelona, and Atletico Madrid are the three strongest teams, and Girona isn't strong enough to beat all the other teams in laliga.
Isn't that what makes La Liga interesting? Instead of seeing Madrid and Barcelona continue to dominate the league, they have another team that they don't expect to be able to compete, which would be fun.
Regarding Gerona, 4 matches without defeat with 1 draw against Real Sociedad. that's good enough for Gerona. but they also got a win against a team that I don't think is very strong. but anyway this is a good momentum for Gerona to collect as many points as they can when they play against weaker teams.
however the new league starts, those who look powerful at the beginning can also be seen to be inconsistent in the middle of the season or even struggle at the end of the season.
You don't really think Girona is in the discussion for championship, right? It would be a miracle if they stay in top four positions ten weeks later, I don't even talk about the end of the league. They only played against low level teams and had a good run, but nothing more.
The only team that can really push Real Madrid and FC Barcelona is Atletico Madrid. They started okay for now, especially that Rayo Vallecano game was crazy. I really like how they played with discipline. I think they have a strong enough squad to play for the championship this season. Griezmann, Memphis, Llorente, Morata, Correa are all top level players a championship team must have. They would push big two but I don't think they'll get the title.
