I was really shocked after the result. Atletico Madrid managed to beat Barcelona away in the La Liga after 18 years...

It isn't a win at Camp Nou though but anyways.
I think the turning point of the game was Raphinha's lob shot hitting the upper post. If he scored there, Barcelona were going to make it 2-0. I think Atletico Madrid wouldn't manage to come back from that.
After that Simeone did his magic somehow again. A last minute winner brought the 2-1 win to his team.

I don't remember exactly but it must be like their 13th or 14th goal that came in the stoppage time this season. They are really in this title competition.
Atletico Madrid's 2-1 win against Barcelona has proven they are in the title race with Real Madrid, and Barcelona. They currently top the La Liga league table waiting for Real Madrid to win or draw their match against Sevilla, to shorten the points gap to one point.
However, Real Madrid is currently winning to Sevilla to 3-1. Mbappe, Valverde and Rodrigo scored Real Madrid three goals before the Sevilla player(Romero) scored their own goal in the 35 minutes of play.
The second half will soon kick off. It's either Real Madrid add more goals or Sevilla tries to equalize Real Madrid. Whichever one, we will get to see to that
It was a spirited performance for athletico Madrid as they overcome their host to win from a goal down to move up to the top of the Laliga table before the years gets to an end but with the way Barcelona are letting others teams to close in on then and even overtake them is surprising as they where once at the top of the Laliga table with some points gap between them and the second placed team.
Athletico Madrid is one team that has surprised me this season as the has return their woess to wining as the club was even at a point in time was even contemplating to sack their manger, but Simone has turn things around for the team
