to be honest, I don't think Atletico Madrid will win this match, Girona is not an easy team especially at home, you can see their last matches at home and they rarely lose, this match can end in a draw, maybe one goal each, or a win for Girona, it's hard to see that happen so I would say a draw is the closest.
Do you underestimate Atletico Madrid?
Even if Girona rarely got a loss at home, doesn't mean Atletico has no chance to get full points today.
Considering the current performance of Atletico Madrid, I believe Atletico Madrid will win this match. They played very well in the last 5 matches, Depay has shown his important role in Atletico squad now. Today, Depay and Griezmann can play together in Atletico attacking line. So, I'm sure this duo strikers will lead to the winning of Atletico Madrid.
Atletico Madrid has a chance to maintain their position in 3rd place, so they must have a big motivation to collect 3 points in this match. If they fail to get 3 points, Real Sociedad will overtake them.
