After successfully beating and eliminating Intermilan from the Champions League, of course I am quite sure if Atletico Madrid will be able to beat Barcelona or at least give a fierce fight in the match, but it turns out that Barcelona can destroy Atletico Madrid very easily
Inter Milan and Barcelona are different teams and they are not the same. Even Inter Milan, if Atletico Madrid have another match with Inter Milan, nothing to be sure that they will win against Inter Milan again.
Barcelona's victory over Atletico Madrid also broke Atletico Madrid's unbeaten record in home games in La Liga this season, since the season began Atletico has won 13 times and drawn once when they played 14 times at home, besides that with this victory Barcelona also recorded now 8 wins and six draws when playing away at once they can coup Girona's position in two currently, The victory over Atletico Madrid I think makes Barcelona will be able to end the season as runners up this season especially in other matches Girona had to lose points to Getafe, thus making Girona's current position even more difficult to continue competing with Madrid and Barcelona.
This win does not help Barcelona to catch Girona and the difference between them is still two points. This defeat costs Atletico Madrid a fourth position as of now, Athletic Club already took over that position and Atletico Madrid will have to try to get it back. Difference between Athletic Club and Atletico Madrid is only one point but with effects from Champions League, Atletico Madrid must play carefully if they want to end the season at least at the fourth position.
